ST-P Plunger Pumps

  • Productivity: 11 ÷ 190 l / hr.
  • Pressure: 3.5 ÷ 20 bar.

ST-P mini plunger pumps up to 190 l / h - 20 bar are designed for dosing chemicals.

The mini-series of plunger (piston) metering pumps ST-P allows you to dispense relatively inviscid and non-abrasive liquids. The exception is models with 3/4 "Gm nozzles and a stainless steel head that dispense viscous (up to 500 cps) fluids.

Pumps are compact in size (relative to other plunger pumps). Self-pump height for all models up to 3 meters.

Plunger (piston) pumps « ST-P » operate with increased back pressure (up to 20 bar) with a capacity of up to 190 l / h. Performance control, including during pump operation, is carried out by rotating the handle of the micrometer screw, which changes the stroke length of the piston (plunger).

On request, models with a servo motor are delivered, which independently rotates the micrometer handle of the pump and is controlled by an input signal of 4-20 mA or 0-10V DC.

The plungers of the pumps have a stroke length of 15 mm and a diameter of 16-30-48 mm, the frequency of working cycles of the piston is 60 or 120 per minute.
