Hydraulic diaphragm metering pump performs well

The Makro/5 HMH hydraulic diaphragm-type metering pump from ProMinent Fluid Controls offers maximum metering capacity from 6000 to 36000 litre/h with a delivery reproducibility of +1%.

The Makro/5 HMH hydraulic diaphragm-type metering pump from ProMinent Fluid Controls offers maximum metering capacity from 6000 to 36000 litre/h with a delivery reproducibility of +1%.

This extensive capacity range can be achieved by multiplexing the pumps.

The pump's power unit is designed to accommodate either a single or two liquid ends giving a capacity of up to 6000 and 12000 litre/h, respectively, at a backpressure of 6bar.

Up to three double-end versions can be coupled together for increased capacity.

The pump is available in four pressure stages: 6, 10, 16 and 25bar.

This modular design allows the pump to be used in a host of different applications.

Liquid ends are available in polypropylene, PVC, Teflon and stainless steel for pumping a wide variety of fluids.

An integrated microprocessor controller processes standard input signals of 0/4-20mA to operate a servomotor actuator for stroke length adjustment.

The controller also allows for manual operation.

A stroke sensor is mounted on to the crank drive of the Makro/5 gearbox.

This allows precise detection of each stroke and can be used in conjunction with an electronic timer to allow the pump to be used for batch metering.

The sensor can also be used with a proportional controller for proportional dosing.

The Makro/5 HMH offers high levels of safety and reliability.

Safety features include patented multilayer diaphragms and integrated thermal overload protection.
