2警告34The electric diaphragm pump is composed of a suction port, a discharge port, a medium chamber and a power assembly. The power assembly is composed of a motor, a crankshaft, a piston and an intermediate shaft 电动隔膜泵由吸入口、排放口、介质室和动力总成构成，动力总成由电机、曲轴、活塞和中间轴构成When the diaphragm pump is working, the left and right diaphragms are driven by the crankshaft and the piston to move left and right隔膜泵工作时，左右膜片均通过曲轴和活塞驱动左右运动The motor drives the crankshaft, the crankshaft drives the piston, the piston pushes the central shaft, and the diaphragm moves to the left. As a result, the volume of the left cavity decreases and the liquid is squeezed out 电机带动曲轴，曲轴驱动活塞，活塞推动中心轴，驱动膜片向左移动，结果是左腔容积减小，液体被挤出。

机械隔膜计量泵（自动加药装置）使用说明书使用前请仔细阅读本说明书，并妥善保管一、综述J xM-IJ XM-II二个系列机械隔膜泵是我厂设计开发的往复式化合物投加泵。

J XM-Ⅰ泵的输送流达500Lh，压力达1.2MPa，取决于泵型号)；J XM一Ⅰ泵的输送流量能力达1400L/h.压力达1MP(取决于泵型号)。

这两个系列泵的特点是机械驱动隔膜，隔膜取消四氟薄膜与橡胶、铁芯复合的结构型式，增大了隔膜行程，冲程调节机构集于可变偏心机构的工作原理，替代了传统的偏心凸轮的有效冲程调节设计形式。

这种设计显著地减小了压力和流量的脉动程度，使流量在10~100%的范围内，稳定性精度可控制在±2%。

1.2、泵的运行原理泵由两大部分组成：动端部分和液力端(泵头)部分。

泵的输出流量取决于传动端的冲程速度，隔膜(泵头)直径和隔膜冲程长度。

在泵运行或停止时，均可以通过凋节冲程调节手轮来改变冲程长度，传动机构根据可变偏心机构原理工作，即电机旋转驱动蜗轮副进行减速，由蜗轮减速部件驱动可变偏心曲轴旋转，可调式偏心曲轴通过连杆将往复式运动传递给隔膜，使隔膜产生挠曲变形。

通过改变连杆上的可变偏心曲轴的位置，就可调转冲程长度。

泵在吸入冲程时，隔膜开始向后运动，泵头内的压力立刻降低；当泵头压力低于吸液管路压力时，吸入口单向阀的阀球被向上“推开”，进口管路中的介质进入泵头腔室内。

当吸液冲程结束时，隔膜运动瞬时停止，泵头内的压力与吸液管路中的压力持平，吸入口单向阀球复位。

泵在排出冲程时隔膜开始向前运动，泵头内的压力立刻升高。

当泵头压力高于排出管路压力时，排出单向阀球被向上“推开”，泵头内的液体进人出液管路，当排出口冲程结束时，隔膜再一次瞬时停止运动。

泵头内的压力与排出管路的压力相同，排出口单向阀球复位，然后再开始下一个循环。

在吸人冲程中，泵头内的压力必须高于物料蒸汽压，如果液体压力低于其气化压力，就会发生气穴现象，影响泵的性能。

It features flow rates up to 13 gallons per minute (13GPM) and is engineered with polypropylene and stainless steel wetted parts, along with seals that are compatible with most agricultural and industrial chemicals as well as lubricants (e.g. those found within power transmission). These wetted materials consist of a polypropylene body and valves, stainless steel fasteners, Hastelloy® check valve springs, Buna‑N, EPDM and Fluorocarbon seals, along with Hytrel® and Santoprene® diaphragms.Sotera utilizes a recognizable naming system where model numbers reference the diaphragm material. Models that begin with ‘SS’ (eg. SS415B) contain Santoprene diaphragms, while models that begin with ‘FR’ (eg. FR410B) contain Hytrel diaphragms. Santoprene is designed for moving agriculture chemicals while Hytrel is used with oils and lubricating fluids. We strongly recommend referring to the Sotera Chemical Resistance Guide foundat to determine proper materials of construction for use with your application.The 400B Series pump is not compatible with strong acids (pH of 3.4 or below), strong bases (pH above 12), non‑diluted flammable liquids with a flash point below 100°F/38°C, or bleach (sodium hypochlorite).• All suction hoses should be reinforced to prevent collapse by system pressure • If there is a possibility of solids or debris within the liquid, at minimum, a 10 mesh screen (0.07") or less needs to be utilized either at the end of the suction pipe or entry into the suction side of the pump. Particles greater than 0.1" will adversely affect pump performance • All suction hoses or pipes must be 1" diameter. Large sizes maybe used as long as it terminates to a 1" diameter at the suctioninlet of the pump• Placement of the suction pipe should terminate 2" from the bottom to avoid particulate contamination unless a 10 mesh in‑line screen is being used as noted• Maximum suction lift capacity is 9 FT (2.7 M) for water at sea level at 70°F. Suction lift for each application will be dependent on the Centipose (cP) of the individual fluid as affected by temperature and elevation• IMPORTANT: Tanks and containers must be vented to prevent collapses • Tighten all non‑metallic fittings to a snug fit to prevent leakage. Damage could occur to the pump if these fittings are over tightened • Do not use the pump as the structural support of the piping system• Be certain the system components are properly supported to prevent stress on the pump parts. As a rule and unless specifically designed into the pump, suction and discharge connections should be flexible to avoid damaging the pump body. Ensure that any connection material is compatible with the substance being transferred through the pump itselfTo maximize performance and longevity of your 400B Series pump, we recommend the following considerations:Installation Best Practices (Suction Side of Pump)• Tuthill strongly recommends grounding the pump and motor priorto any usage • Electrically bonding to a vehicle frame or utilizing a ground circuitfor stationary applications are preferred grounding methods. Alwaysconsult with a licensed electrician for your application • Inspect any and all power and grounding cables prior to each use.Replace if the outer protective jacket has been removed to exposeany wires• For 12V DC non‑explosion proof motors, the power cable terminates with battery clamps that are either red (+) or black (‑); however a ground wire is not included • For 12V DC explosion‑proof motors, in general, neither a ground wire, power cable, or battery clamps are provided. See pages 14‑15 forspecific included components • DO NOT connect the ground wire to the negative post of the DC power sourceElectrical InstallationBLACK−RED+GREEN 23EARTH / CHASSISGROUND• All discharge hoses should be a minimum of 1" diameter. Large sizes may be used as long as it terminates to a 1" diameter at the discharge outlet of the pump • Hoses greater than 20' may be used, however, reduced outlet flow at the end of the hose or nozzle should be expected. Flow is dependent onthe cP of the fluid as affected by temperature and elevation• Always use hoses and accessories that are compatible to the product being transferred. For hoses, as a general practice Tuthill recommends EPDM for agricultural chemical and Nitrile or Buna‑N for petroleum‑based oils and lubricantsInstallation Best Practices (Discharge Side of Pump)Utilizing the diagram above, proceed with the following connections:1. Ground connection (green clamp or eyelet)2. Negative connection (black clamp)3. Power connection (red clamp)AC Power• 115V AC, 60Hz, 2.5 amps, 1/4 Hp (185 watts) motor, standard non‑explosion proof• 115V AC, 60Hz, 2.5 amps, 1/4 Hp (185 watts) motor, explosion proof uL listedAvailable AC Voltage ClassesDC Power (continued)• All non‑explosion proof 12V DC models come with a preinstalled power wire. 12V DC models will have a 30 amp fuse holder and fuse • 12V DC and 24V DC explosion‑proof models will not have a power cord installed but may include a power cable separately, depending onmodel configuration• All non‑explosion proof 110V AC models come with a preinstalled power cable. These models will terminate with a type B (3 pin) grounded, 15A plug that is compatible with type B sockets • 110V AC explosion‑proof models will not have a power cord installed but may include a power cable separately, depending on model configuration as outlined on pages 14‑15Routine Maintenance Schedule1. Always check oil level by the sight glass prior to any fluid transfer. The ideal oil level should be at the mid line or halfway point of both site glasses. Add SAE 30W oil as needed to maintain thenecessary level 2. Inspect all external Torx(r) head screws are tight. If any screws appear to be loose, torque to 75 in‑lbs3. Inspect all motor flange hex head bolts are tight. If any bolts appear to be loose, torque to 50 in‑lbs4. Either annually or after 500 hours of usage, drain the existingSAE 30W weight oil through a site glass port and replace withapproximately 16 oz of the same oilRegular maintenance is critical to maintaining performance and extending the life of your 400B Series pump.• Always turn off the transfer pump and disconnect from a power source prior to servicing • Always flush the pump completely prior to any service or disassembly. Tuthill recommends the use of water for flushing agricultural and industrial chemicals. For petroleum‑based products such as oils and lubricants, flushing with diesel fuel is acceptable • DO NOT PRESSURIZE THE FLUSHING FLUID. Damage to the pump will occur. Instead, submerge the suction tube or inlet adapter in the flushing fluid, then operate the pump as normal for approximately 15‑30 seconds or until the flushing fluid returns to its initial color. Allow the pump to air dry prior to any service • DO NOT SUBMERGE THE ENTIRE PUMP OR ELECTRICAL MOTOR IN THE FLUSHING FLUID, ONLY THE SUCTION TUBE OR INLET ADAPTER • Do not allow chemicals, lubricants, or oils to remain in the internal pump cavity for any extended period of time. Crystallization or a glum could become present, adversely affecting pump performance • Tuthill highly recommends flushing the pump after each use to avoid ‘dry out’ and contamination between fluid transfers• The interior pump cavity is filled with SAE 30W oil by the factory in order to lubricate the internal gear drive mechanism and yoke assembly. Certain pump repairs will require the draining of this fluid. If necessary, remove one of the site caps found on the exterior of the pump body and drain the oil through this port. Replace with new SAE 30W oil after repairs are completed through the same port. Tuthill recommends 16 oz of oil to be placed inside the cavity or until level is halfway within the site glassBest Operational PracticesMotor with Gear Assembly Removal1. Position the pump with the sight caps downward2. Remove the four (4) screws holding this assembly and lift upward3. Replace with new motor and gear assembly as supplied by TuthillGear Assembly Removal1. Remove motor as noted above2. Remove six (6) screws and key holding the gear pack assembly on the motor shaft3. Replace with new assembly, install new screws, and key1. Turn the pump on its side by which the diaphragm to be repaired is facing upward while the opposite diaphragm is facing downward2. Remove the eight (8) diaphragm cover screws. This will require a Torx T30 bit3. Remove the cover and turn it over to expose the inner side to avoid any contamination. The cover will have a gasket seal. It is highly recommended that this seal be replaced during this repair4. Remove the four (4) retainer screws with a Phillips #2 screwdriver.These screws have a seated O‑ring. It is recommended to replace boththe screws and O‑ring during this repair5. Remove the diaphragm assembly by pulling on the four edge corners ofthe diaphragm itself, being careful to not tear or curl the diaphragm.If necessary, pulling on the check valve assemblies is acceptable. Donot use any tools to pry the diaphragm off the pump body as this coulddamage the surface of the pump. Be sure to retain the four (4) checkballs that are within the cavity of the pump. These may be removedwith the diaphragm6. Install new diaphragm assembly in the same orientation as the one that was removed. Important that the check balls are seated prior tothe diaphragm assembly placement7. Insert the four (4) Phillips head screws and tighten to 35 in‑lbs8. Install the diaphragm cover with installed gasket. It is important to hand start all external screws prior to driving to a torque specification of 75 in‑lbsDiaphragm Assembly ReplacementBoth the diaphragms and check valve assemblies can be serviced without removing the oil from the interior pump body cavity. It is important that only one(1) assembly be serviced at a time. Avoid any possible contamination of the oil within the internal pump cavity during this repair.ProcedureInternal Mechanical Components (Bearing Plate, Yoke, and Drive Shaft Assembly)1. Remove motor and gear assembly from pump cavity2. Drain oil from interior cavity through this opening3. Remove four (4) screws holding bearing plate4. Remove bearing plate, allowing for the thrust plate to be removed as well5. Remove drive shaft, bearing, bearing ring, and yoke assembly.IMPORTANT: the yoke assembly is under pressure by two springs.Do not attempt to repair, only replace with factory authorized parts6.

SUCTION LOSSES: Test pump was mounted on a 55 gallon drum of oil, 1/2 full. A Sotera 1" suction pipe was used. A longer or smaller diameter inlet pipe will lower the flow rate.2. VERTICAL HEAD LOSSES: Test hose was horizontal with pump. Add 3feet of hose for each 1 foot of vertical rise. 3. OTHER LOSSES: Elbows, quick‑disconnects, swivels, and check valves in outlet or inlet hoses will restrict the flow. Add the estimated length of hose for each component used.Fluid Compatibility by Diaphragm (Typical)308 cps(30 wt Oil @ 69°F)560 cps(30 wt Oil @ 56°F)665 cps (30 wt Oil @ 49°F)2420cps (30 wt Oil @ 22°F)Anti-Drip Nozzle Spout Kit 400KTF0237For use with Norwesco and other nozzles with a 1 3/16" outside diameter. Installation1. If there is a raised plastic notch on the nozzle, carefully remove itwith a file before installing the anti‑drip spout2. Apply soapy water to the end to aid in the installation. Place theanti‑drip spout on the nozzle as shown at right. Tap the spout with a rubber mallet until it is fully engaged. The space between the end of the spout and the bend in the nozzle should be slightly more than1 3/4" when pressed fully into placeProper UsePlace the nozzle into the container to be filled BEFORE turning the pump on.After pumping, shut off the valve handle then gently shake the nozzle BEFORE removing it from the container. The spout will open when it senses pressure greater than 1 psi. Flow restriction will be minimal.
