Description Cavity Style Gear Pumps - Series GAT, GD, GJ, GK, GL, GM, GN Cavity-style gear pumps are rotating positive displacement pumps. The main pump components are fabricated of a variety of machined metal components, the gears and bushings are molded or machined from plastics, and a variety of perfluoromers and elastomers are used for the static seals. There are no dynamic seals. These pumps are magnetically coupled to their drive. The driven magnet is fixed to the driving gear shaft .
Description (continued) Piston Pumps - Series PD, PF The Series PD and PF pumps are reciprocating piston pumps. The Series PD pumps use a pair of pistons and a rotating valve to positively displace fluid. The Series PF uses a single reciprocating and rotating piston without valves to positively displace fluid. The main pump components are fabricated from a variety of machined metal and ceramic pistons, molded and machined plastics and elastomer seals. Piston seals are dynamic and other seals are static.
Assembly Proper assembly is required to prevent magnet rub due to misalignment. Loose pump head or adaptor bolts may cause misalignment which may result in magnet hub rub on the magnet cup causing high surface temperatures or weakening the pressure boundary created by the magnet cup. If the pump head housing assembly and motor are supplied separately they will need to be assembled prior to the installation.
Filtration CAUTION The pump can be damaged if the fluid being pumped has abrasive suspended solids. Always install a suitable filter or strainer when these fluids are being pumped. All strainers and filters should have large surface areas to prevent excessive pressure drop. For open systems the filter must be installed on the inlet side of the pump. For closed loop systems the filter can be installed on the inlet or discharge side.
Fittings It is recommended that the pipe fittings are connected to the pump before the pump/ motor is fitted into the installation. The following should be observed when connecting pipe fittings: • Pipe sealing compound or PTFE tape should be applied to the threads to prevent leakage. • Apply sealant or tape sparingly to prevent a build up of excess material which may dislodge and clog the pump. Two wraps of PTFE tape are usually sufficient.
Piping High system pressure may be experienced if the pump outlet is blocked, e.g. by a closed valve downstream. Ensure that a pressure relief valve is fitted to the system if the pump is capable of exceeding maximum system pressure. Piping must not exceed flash point temperature of the area. Misaligned piping may apply a load to the pump head pulling it out of alignment with the motor. Do not force piping into position.
Electrical Connection (where applicable) Refer to the installation instructions supplied with the motor for connection details. Electrical installation must be carried out by qualified personnel who are conversant with local electricity installation regulations. Before starting any electrical installation work ensure that the main electrical supply is adequately isolated.
Operation Starting or running the pump with the discharge valve closed will overload motor resulting in overpressure in the discharge pipe. Extended periods of dry running may result in permanent damage to the pump and may cause surface temperature to exceed the operating temperature of the pump. Ensure that the pump head temperature does not exceed the flash point temperature of the fluid or area. Shut down pump for no fluid condition. Shut down pump for no flow condition.
Bypass (Optional) Pumps equipped with internal bypass will recirculate fluid increasing the amount of fluid through the bypass, which will increase the heat produced. Ensure when operating at bypass conditions that the pump does not exceed flash point temperature of area or pumping liquid. Micropump recommends the pumps are not operated continuously with 100% bypass recirculation.
Magnet Decoupling How to Recognize Magnet Decoupling Magnet decoupling occurs when the load on the pump exceeds the coupling torque between the magnets. The magnets are forced out of pole-to-pole alignment and are decoupled. When decoupling occurs, the driving magnet speed increases to motor noload speed while the driven magnet and pumping parts remain motionless. NOTE Decoupling is an inherent feature of magnetic couplings and DOES NOT indicate a pump failure.
Maintenance Excessive wear to pump can result in driven magnet rub on the magnet cup. This can generate high surface temperatures or degrade the capability of the pressure boundary. Remove the pump from service and replace or repair if pump performance degrades significantly or the pump becomes noisy. Excessive wear to motor can result in driving magnet rub on the magnet cup. This can generate high surface temperatures or degrade the capability of the pressure boundary.
Fault Isolation If the pump does not meet its design performance or fails to operate correctly, refer to the following tables for assistance in identifying the cause and remedy: PUMP PRODUCES NO LIQUID AT STARTUP Cause Remedy Inlet valve closed. Discharge valve closed. Open inlet valve. Open discharge valve. Pump does not reach speed. Magnets decouple. Check motor is running. Open inlet & outlet valves. PUMP SEIZES IMMEDIATELY AT STARTUP Cause Remedy Solids present in pump.
Technical Specification CAUTION Operating temperature range of some configurations and material selections may be more narrow than those listed. Contact your local Micropump distributor or contact Micropump directly for information. All Dimensions in mm.[inch] NOTE Pump and drive dimensions may be summed to determine total unit dimensions. NOTE Not all mounting configurations are shown. Contact your local Micropump distributor or contact Micropump directly for additional versions.
