Hydraulic Metal Diaphragm Metering Pump ORLITA MHHP

Capacity range of a single pump: 3 – 4 l/h; 3000 bar

The metal diaphragm metering pumps ORLITA MHHP are special pumps, which provide precise pump capacities even at maximum pressures of up to 3000 bar.

Product description

Reliable capacity even at maximum pressure

The hydraulic metal diaphragm metering pumps ORLITA MHRH 150 have a metal diaphragm, which is designed to meter precisely at maximum pressures of up to 3000 bar. Only in this way can excellent process reliability be ensured.

Your benefits

Excellent process reliability:

  • Metal double diaphragm with integrated diaphragm rupture warning / signalling system ensures precise and low-wear operation even at extremely high pressure in areas not at risk from explosion
  • The product chamber is hermetically separated from the hydraulic part
  • Integrated hydraulic relief valve and automatic vent valve for the hydraulic chamber
  • Wear-free, valveless enforced anti-cavitation of the hydraulic leakage guarantees optimum dosing precision
  • The dosing precision is better than ± 1 % within the 10-100 % stroke length range under defined conditions and with correct installation
