API 675 DOSERINGSPUMPER

MEMBRANE DOSING PUMPS

Dosing pumps meet the market's needs from shaft pumps to complete or injection systems.
The production offers different capacities in diaphragm and piston dosing pumps from small quantities in measured in ml to 10,000 t/l and working pressures up to 1200 bar.

Dosing pumps are manufactured and pumps are designed for special needs and deliver packaged measuring systems complete with all necessary accessories such as:

Pumps are manufactured according to API standard 675.

Positive return of the piston stroke makes it possible to achieve a low NPSH value under all operating conditions.
Stroke adjustment can be manual or automatic with pneumatic or electronic servo control both with the pump running and stationary.

Variation in capacity range is achieved as follows:
– range 10 – 100 % for stroke adjustment
– range 5 – 100 % using a mechanical or electronic converter VFD (Variable Frequency Drive) that allows pump speed variation with precision below 1 %.

Stamp type with:
single or double valves:
hydraulic heads with double power piston.

Diaphragm type with hydraulically activated diaphragm that has:
single or double membranes
-detection of membrane rupture
-built-in safety valve: automatic extraction of leaks.

Wide selection of components construction materials (AISI 316, titanium alloy, CrNiMo, super austenitics, PVC and others) ensures the most suitable solution for each specific application.
