Everest Metering & Dosing Pumps
EVEREST Metering Pumps are high precision positive displacement pumps, as per API 675 code. The discharge can be varied from zero to maximum capacity (0- 100%) while pumps are running. Everest Metering pump capacity is almost independent of the discharge pressure.
DIAPHRAGM TYPE METERING / DOSING PUMPS
Diaphragm Pump heads are recommended for critical, abrasive toxic or poisonous or Flammable liquids where any product leakage is not acceptable.
The reciprocating plunger displaces hydraulic fluid causing movement of the diaphragm and a like movement of the process liquid. The diaphragm separates hydraulic fluid and process liquid. A pressure limiting valves prevents overload of the pump. The internal leak age at the plunger is balanced by the leakage replenishment valve. Thus, the diaphragm always operates in an optimal operating range. This diaphragm control gives very high operational safety.
The diaphragm has a long life as it is always in hydraulic balance with the liquid being pumped on one side and hydraulic oil on the other side. The system is safe guarded by a built in pressure relief valve on the hydraulic side.
Both types can be offered in Duplex or Multiple heads for different chemicals with a common motor. Each head has independent connections and the capacity of each head can also be independently adjustable.
