Entrained liquid drops, Condensible vapours, or occosoinal slugs of liquid can be handled without damage to the pump or significant effect on capacity. In the case of vapours, the pump can also serve as a condenser.

No lubricant or oil is required within the pump it self. Thus the air or other discharge gases are not contaminated. The liquid which froms the ring (usually water) serves bothe as a sealant and a pumping media.

A wide selection of materials and seal liquids can be used when corrosive gases and vapors are being pumped

The pumps contain no metal parts that rub against each other. Packing glands and bearings are accessible from the outside. There is no clearance volume and the pumping action is smooth and uniform (non-pulsating).

The only moving part is a balanced impeller which reduces noise and vibration. This means lower foundation, installation and serviec costs.

The pump can be provided with partial liquid recycle, closed loop liquid operation, automatic control and other features.

Mechanical seals can be provided as an option.

Small entrained solid will pass through the pump. However, abrasibve particles will result in reduced pump life.

Each pump is performance tested prior to shipment.
