Willett Pump

Specifically designed for the arduous duty of pumping ceramic slip, the “Willett” positive displacement vertical ram pump has a long and distinguished history in this industry. This sturdy unit is used in 1,000’s of installations throughout the World on transfer duties, filter press feed and for feeding casting slip ring mains.

The pump’s hydraulic power pack gives automatic flow control when feeding filter presses and fixed flow when feeding casting slip ring mains. The hydraulic drive ensures minimum power usage regardless of flow or pressure.

Inlet/outlet valves can be the gravity seal ball type or the spring loaded “Stalk” design. Ball valves are usually polyurethane covered cast iron with solid polyurethane seats. Stalk valves can be offered with nylon coated and stainless steel components.

For applications where it is essential to avoid contamination fully lined pumps are available.
