NOV Mono® CP Range Pumps

Simple design. Sturdy lightweight construction. Conveniently compact.

Whether for domestic pumping requirements, or light industrial duties - they’ll keep up with the pressure of work!

Four models available (CP11, CP25, CP800 and CP1600) each operating on the well proven “progressive cavity” principle, and between them a variety of performance capabilities, up to a maximum capacity of 1650 gph (125lpm), and pressures of up to 92 feet (28 metres).

Stator Models in the range

• Natural.
• Nitrile (Standard).
• Hypalon.
• High Nitrile.
• Fluoroelastomer (CP11 and CP25 only).

The NOV Mono® Principle

The CP uses the famous helical rotor pumping principle.

The heart of the Mono Pump is the single helix metal rotor which rotates eccentrically within a double helix resilient stator of twice the pitch length of the rotor. The rotor of circular cross section creates a continuously forming cavity as it rotates. The cavity progresses towards the discharge end, advancing in front of a continuously forming seal line, carrying the pumped material with it. As the stator open cross sectional area is always constant the flow rate is continuous without pulsation.

The Principle Benefits are:

• Capacity is proportional to speed.
• Self priming even with entrained air.
• Can handle a variety viscous materials.
• Minimal damage to shear sensitive products.
• Can handle liquids containing solids or abrasive particles.
• Pulsation free operation.
• Positive displacement.
