Diaphragm Pumps

Mechanically Operated pumps use a heavy duty worm and wheel reduction direct coupled to an eccentric to actuate the diaphragm. A primary Vee belt drive allows the pump to be driven by any power source.

Pumps are available with 240/415Volt motors and EXD or EXE rated motors for hazrdous zones.

Features

• Suction lifts to 7.5 metres.
• Rapid self priming and will run dry without damage.
• Will handle abrasive liquids and pass solids up to 80% of the port size.
• Heavy duty construction yet is compact lightweight and portable.

 Progressive cavity Pumps

CP Range of pumps use the helical rotor pumping principle . The heart of the Mono Pump is the single helix 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.

Features

• Self priming even with entrained air.
• Minimal damage to shear sensitive products.
• Huge range of flow rates.
• Suitable for use with Oil Water Separators.
• Can handle liquids containing solids or abrasive particles.

 Submersible Pumps

The Davey range of submersible pumps are used for water transfers, pumping of grey Water,sump emptying, pumping of light slurries and factory waste.

Features

• Able to pump soft solids in suspension.
• Less susceptible to blockage.
• D15VA models feature a special recirculation port to keep soft solids agitated in sump, improving ability to pump away such solids.
• Automatic resetting thermal overload.
• Oil resistant leads, 10metres long with 3 pin power cord.
