Product Description
DOSING / METERING PUMP:
Dosing Pumps are positive displacement Pumps. The discharged can varied from 0 to 100 capacities white pumps are running or at rest. Our pump design makes it an ideal flaw control element in chemical process for feeding chemicals with a high degree of accuracy, under any discharge pressure condition. They are of robust design, unmatched quality and offer considerable saving due to small space requirements, low installation cost and minimum maintenance.
Special Features for Dosing Pumps:
Pumps can he offered in simplex, duplex or multiple heads for handling different chemicals with a common motor. Each head would have independent connection and the capacity of each head can also be independently adjustable.
DIAPHRAGM TYPE HEAD METERING:
Hydraulically operated Diaphragm type head are suitable for service conditions involving hazardous toxic, radio active or poisonous liquid where product leakage is not at a11 permitted. The Diaphragm is Hydraulically actuated and has a long life as it is always in hydraulic balance, with the liquid being pumped on one side and actuating fluid on the apposite side. Its function is basically that of the partition. The diaphragm material is usually Teflon or Synthetic rubber. The system is safe guarded by the built in relief vacuum valve on the hydraulic side. For very severe duty condition or handling slurry or hot liquids and remote
type heads can he provided.
Liquid end Material for Dosing Pumps
Wetted parts can be offered in: Stainless steel 304 P. P. Stainless steel 316 Teflon
ROTARY GEAR PUMPS:
GENERAL
All types of Gear are providing positive displacement of the fluid being handled Discharge directly proportionality to the speed and substantially independent of delivery head.
If a gear not pump is not provided with a safety device or relief valve and discharge valve is closed while the pump is in operation; the pressure may built up in the pump until the casing with burst or power source is stalled and therefore Gear Pumps can not be operated against a close discharge valve. Gear pumps are suitable for handling wider variety of fluids from very lowest to very high viscosities.
Gear pumps are used in all industries like food processing plants, oil refineries, soap factories, distilleries, wineries, breweries, power generations, on earth movers, tractors, tippers and various hydraulic services.
WORKING PRINCIPLE:
Gear Pump consists of a fixed casing containing gears operating with minimum clearance. Instead of throwing liquid as incase of centrifugal pump, gear pump traps the liquid between the gear teeth and close casing on the suction side and carries it around to the discharge side from where it is forced out in to the discharge side. Gear pumps discharge smooth flow.
