Product Description
Two-Screw pump up to PN 16, verticalSelf-priming vertical screw pump for non lubricating liquids
The Houttuin double entry twin screw pumps series 211.40 are vertical 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 unequalled suction power.
Construction
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
Single unbalanced mechanical seals keep the liquid to be pumped isolated from the bearings and the gearbox.
Overload protection
For protection against overload a built-on spring loaded relief valve can be supplied.
Applications
For pumping contaminated or slightly abrasive, lubricating and non-lubricating liquids of low or high viscosity which do not chemically attack the pump materials (corrosion proof materials can be offered). In the chemical and petrochemical industry, soap- and grease industry, paint and lacquer industry, food and beverage industry, plastics industry, sugar industry, environmental technology, in tank farms and in the shipbuilding industry.
