SCREW PUMPS

WORKING PRINCIPLES

"Precision" positive displacement Screw Pumps consist of Screw like rotor which revolves in double threaded stator of resilient electro metric material. While in operation rotor rotates within the stator creating cavity progressively from the suction to discharge end with a sealing line between suction and discharge, fluid entering the cavity thus convey positively and progressively..

UNIQUE CHARACTERISTICS

PRECISION Positive displacement screw pumps are self priming with built in suction positive.

Displacement and revolutionary in pumping all kind of fluids.
1.Self Priming: Build in self prime at 27 Ft of suction lift with Powerful suction.
2.Positive Displacement: Rotor exerts positive pumping of infinite length and the head developed is independent of the speed ,capacity is proportional of the speed.
3.Meeting uniform Flow: Uniform discharge without pulsation and displacement changes with discharge pressure.
4.Low Velocities: All liquid are handled with minimum turbulence agitation or pulsation no formation.
5.Handle solid in Suspension: High percentage of solids suspended in liquids are handled freely.
6.Handle Particles: Solid particles are been handled without damaged.
7.Reversibility: Pumps in either direction with equal efficiency. Pump in and pump out by simply changing direction of rotation and v/v can be change of piping, but valves in lines should be taken into consideration.

TYPES OF PUMPS

PEC series Pumps are standard design for all branches of industries, capacity ranging from 50 it to 30000 Lt/hr, discharge pressure upto 5 Kg/cm2, 2PEC series Pumps output up to 15000 Lt/Hr, discharge pressure up to 10 Kg/cm2.

A. CONTAINER PUMPS (GLANDLESS)
The pump unit flanged to the bottom of the container, drive is transmitted through the container from driver unit on the top, versatile in pumping hick media which are not self feeding, capacity ranging from 50 Lt. to 10000 Lt/Hr

B. VERTICAL SUMP PUMPS
Submersible Pumps for thick Medias like settled sludge, pastes, industrial effluents, activated sludge etc. Advanced and versatile, light weight tubular design with high tolerance of entrained air and gases.

C. FEEDER HOPPER PUMPS (SOLID PUMPS)
Upstream Feeder Hopper Pumps ideal for media which are almost dry and heterogeneous which do not flow into the Pump by themselves.

D. SANITARY PUMPS
Quick clearing Pumps used for food and beverage, pharmaceutical etc. Easy to dismantle, reassemble and clean.
