The diaphragm type metering pump uses a diaphragm to realizes reciprocating motion under the action of the driving mechanism, and complete the pump for the suction and discharge progress.

• No moving seal, no leakage.
• It can transport high viscosity, abrasive and hazardous chemical liquid.
• The quality PTFE diaphragm is pressed into multi-layer composite structure.
• Pump pressure is less than 1.2Mpa.
• PVC, SS314, SS316, SS316L, PTFE, PVDF pump head is available.
• Single phase/3 phases, 50Hz/60HZ motors are available, class F, IP55.
• Variable frequency motor and stroke controller for remote adjustment are available.

The piston metering pump is also called plunger metering pump. The piston metering pump can periodically change the volume of the working chamber by reciprocating straight line of the pump plunger. For this pump, a seal packing is requested.

• High pressure, max to 50Mpa.
• High accuracy, the precision error within 1%.
• Max viscosity up to 2000cps, max temp to 120 C degree.
• Pump body material in SS304/SS316/SS316L.
• Pump plunger made of ceramic or SS316 coated with ceramic. 
• Heat jacket or cooling jacket can be provided.
• Single phase/3 phases, 50Hz/60HZ motors are available, class F, IP55.
• Variable frequency motor and stroke controller for remote adjustment are available.
• Especially used to deliver the liquid with high viscosity, high pressure and high temperatures.

The hydraulic diaphragm metering pump has a reciprocating diaphragm in a hydraulic oil chamber, in place of reciprocating piston inside a cylinder to produce the pumping action of the reciprocating positive displacement pump.

• High press, max up to 30Mpa.
• High accuracy, adjustment accuracy +/- 1%.
• No leakage, no seal packing requested.
• Handling liquid temp range, -20 to 100 C degree.
• Pump head material in SS304 or SS316.
• Heat jacket or cooling jacket are both available.
• Pump includes an internal safety valve.
• Double diaphragm with leakage detection is optional.
• Single phase/3 phases, 50Hz/60HZ motors are available, class F, IP55.
• Variable frequency motor and stroke controller for remote adjustment are available.
• Especially used to deliver the liquid with strong corrosive, volatile, flammable and explosive, highly toxic, radioactive.
