Plunger Metering Pump ORLITA PS

Capacity range of single-head pump: 0 – 2800 l/h, 800 – 11 bar

The high-performance plunger metering pump ORLITA PS enables precise pump capacities even at maximum pressure and temperatures of up to +400 °C. The ORLITA PS pump has a modular construction and is therefore very flexible.

ORLITA PS – Simple, Robust and Reliable.

ORLITA PS plunger metering pumps (PS 35 to PS 600) with a stroke length of 20 to 40 mm provide a capacity ranging from 0 to 2800 l/h at 600 – 11 bar. A wide range of drive versions is available, including some for use in Exe and Exde areas with ATEX certification. The ORLITA PS product range is designed to comply with API 675. Its modular construction permits the free combination of drive units, drives and dosing heads, producing a pump for a range of different feed rates and media operating at different working pressures.

Your benefits

Flexible adaptation to the process:

Precise capacity even at maximum pressure
The dosing precision is better than ± 1 % within the 10-100 % stroke length range under defined conditions and with correct installation.
Cone valves for use as suction and/or discharge valves with minimal wear, good self-cleaning and low pressure loss (NPSHR)
Excellent hydraulic efficiency

Excellent flexibility:

The modular construction ensures a wide range of uses
It is possible to combine up to 6 metering units, even with different pump capacities, in multiple pump systems
