Hydraulic Diaphragm Metering Pump ORLITA MH

Capacity range of single pump: up to 320 l/h, up to 780 bar

The diaphragm metering pump ORLITA MH has a robust metal diaphragm. This permits precise pump capacities even at very high pressure. The ORLITA MH has a modular construction and is therefore very versatile. For example, a range of drive versions is available and drives and dosing heads can be freely combined.

Product description

Reliable capacity even at very high pressure

ORLITA MH hydraulic diaphragm metering pumps (MHS 35 to MHS 600) with a stroke length of 15 to 40 mm provide a capacity range of up to 320 l/h at pressures of up to 780 bar. A wide range of drive versions is available for use in areas at risk from explosion with ATEX certification. The ORLITA MH 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

Excellent process safety and reliability:

  • Metal double diaphragm with integrated diaphragm rupture warning system ensures precise and low-wear operation even at very high pressure
  • The product chamber is hermetically separated from the hydraulic part
  • Integrated hydraulic relief valve and automatic bleed valve for the hydraulic chamber
  • Wear-free, valveless enforced anti-cavitation of the hydraulic leakage guarantees optimum dosing precision
  • Cone valves for use as suction and/or discharge valves with minimal wear, good self-cleaning and low pressure loss (NPSHR)

Excellent flexibility:

  • It is possible to combine up to 6 metering units, even with different pump capacities, in multiple pump systems

Field of application

  • Oil/ gas production (onshore/offshore)
  • Chemical/Petrochemical industry
  • Pharmaceuticals & cosmetics
  • Food production
  • Packaging industry (bottling pumps)
