Self-priming submergible screw pump for lubricating liquids
The Houttuin double entry twin screw pumps series 215.10 are vertical rotating self priming positive displacement pumps. The pump is constructed for subergible application and has therefore a very good NPSH-value. Two inter-meshing screws rotating in a pump casing ensure high pumping efficiency with constant axial flow and unequalled suction power.

Construction

The spindles are supported and axially held in position by ball bearings. The transmission of torque from the driven spindle to the idler spindle is effected by product lubricated timing gears in an attached gearbox. The ball bearings and timing gears maintain a small clearance between the screws, thus preventing metal to metal contact.

Shaft sealing

Product lubricated single unbalanced mechanical seal

Overload protection

For protection against overload a built-on spring loaded relief valve can be supplied.

Applications

For pumping lubricating oils, hydraulic oils or other lubricating fluids which do not contain abrasive substances nor chemically attack the pump materials. As lube oil pump in ship and offshore engineering, as filling pumps in tank farms and in hydraulic systems.
