Product Description

Two-Screw pump up to PN 16, horizontal

Self-priming two screw pump suitable for low pressure applications

The 216 series provides customers a time-tested, globally adopted self-priming two screw pump suitable for low pressure applications for both clean and abrasive fluids. The 216 offers:

• 60+ years of global, field proven reliability

• Non-contacting rotors for abrasives handling

• Field replaceable liner and ‘pop-out’ rotor access for ease of inspection and maintenance

• Optional, mounted relief valve for overpressure protection

The 216 is suitable for a host of duties within process and transport applications for the chemical, food and beverage, oil and gas, petrochemical, power, shipbuilding and other general industries. It is available in a variety of materials, including cast and stainless steel, to meet your specific requirements.

The Houttuin double entry twin screw pumps series 216.40 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 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.
