Self-priming horizontal screw pump for non lubricating liquids

 

The Houttuin single entry twin screw pumps series 136 are horizontal rotating self priming positive displacement pumps. Two intermeshing 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 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 fat industry, paint and lacquer industry, food and beverage industry, plastics industry, sugar industry, shipbuilding, environmental engineering (e.g. for removal of wast oils, solvents and chemicals) etc.
