EVEREST offering Metering Pumps are high precision positive displacement pumps,
as per API 675 code. The discharge can be varied from zero to 100 %
capacity while pumps are running. Metering Pumps capacity is almost
independent of the discharge pressure
Type Metering / Dosing Pumps
Pumps head are recommended for critical, abrasive,
toxic or poisonous or flammable loquids where any products leakage is
not acceptable.
Working Principle
The reciprocating plunger displaces hydraulic
fluid causing movement. and a like movement of the process liquid. Its
separates Hydraulic fuild and process liquid. A pressure limiting valves
prevents overload of the pumps. The internal leak age at the plunger is
balanced by the leakage replenishment valve. Thus it always operates in
an optimal operating range, It controls gives very high operational
safety.
It has a long life as it is always in hydrauclic
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.
Technical Specification
The following chart gives a quick reference of EVEREST Metering Pumps Models. However pumps can be manufacture to meet
specification capacities in terms flow rate and discharge pressures
