Single screw pumps

Also known as

Single Helical Rotor Pump

Progressive Cavity Pump

Eccentric Screw Pump

Working Principle

The pump design consists of a single helical external threaded metallic rotor that rotates eccentrically inside a double helical internal threaded elastomeric stator of the same minor diameter and twice the pitch length.
Interference fit between the metallic rotor and the elastomeric stator form a series of sealed cavities 180° apart, that progresses from suction to the discharge end as the rotor rotates inside the resilient stator, thereby gently carrying the medium.

Salient Features of Single Screw Pumps

	Capability to handle high solid contents with fibres & solid particles up to 40mm size.
	Capability to have high suction lift (up to 8.5 mwc).
	Capability of variation in flow rate by just changing the pump speed.
	Good self priming properties even with air or gas inclusion.
	Capability to develop high-pressure heads.
	Capability to deliver very accurate dosages given appropriate drive controls.
	Lower fluid velocity and so lower wear rate.
	Simple construction and high reliability of operation.
	Easy and quite maintenance, which does not require any special tools.
	Steady and smooth flow enhances negligible pulsation.
	No foaming.
	No foot value is required.
	High efficiency for viscous fluids resulting in higher saving of power.
	Pressure head is independent of speed while capacity is dependent on speed.
