Self-priming horizontal screw pump for lubricating liquids


The Houttuin double entry twin screw pumps series 216.10 are horizontal rotating self priming positive displacement pumps.Two inter-meshing screws rotating in a pump casing insert ensure high pumping efficiency with constant axial flow and unequalledsuction power.



The spindles are supported and axially held in position by ball bearings. The axial thrust incurred is absorbed by the  amply sized axial shaft bearings. The transmission of torque from the driven spindle to the idler spindle is effected by oil-lubricated timing gears located outside of the pumping area 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 

In standard design the pump is fitted with a single unbalanced mechanical seal, with fluid chamber if required.


Overload protection 

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



For pumping lubricating oils, hydrailic 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.
