Ease of use and maximum reliability
The PDM 71 metering pump can be equipped with all the automatic regulation system.
It has been designed and constructed to meet the most varied metering demands of liquids and chemical reagents.
It inherits the motorization and the lightweight alloy body from the plunger metering pump PD 71
existing in Sodi Scientifica’s products portfolio for many years and known as an extremely reliable and performing product.
This pump features simple and tested operating principles, yet it does not forgo the high metering precision that characterises all Sodi Scientifica pumps.
Its sturdy and compact structure assures high performance in heavy duty applications and makes its maintenance very straightforward.
Manual Flow Regulation
Manual regulation when stationary or in motion with automatic regulation option. Diaphragm stroke length is regulated through a manual rotation of an adjustment knob. The analog indicator shows the pump instantaneous flow rate.
Automatic Flow Regulation
The pump can be controlled by means of an electromechanical self-regulator or by means of Pulse Width Modulation (PWM), or equipped with a servo-ventilated motor and inverter.
Accessories on demand
A wide number of accessories are available on demand, such as, just to name a few, self-regulator with 4-20 mA signal, PWM, high foot support, injection valve, flexible hose and many others.
