Long-life, low-maintenance positive displacement ram pump for difficult/abrasive sludge and slurries.
Overview

The Willett™ Pump is a vertical, single-acting positive displacement ram pump, designed for long life, low maintenance and optimum energy efficiency. It is the most cost-effective solution available on the market to pump difficult and abrasive sludge and slurries. It can be either hydraulically or mechanically driven, and is supported by a rapid-response service from a highly qualified team of engineers, who are available around the clock.

The latest design improvements to the Willett™ Pump are available as retrofit packages, which can be fitted to existing pumps. Retrofit can be carried out on site with minimal downtime. The benefits are easier maintenance, improved control and greater efficiency, leading to reduced costs.

What is a Hydraulic Ram Pump?

A major advantage of hydraulic ram pumps is that they don't need an external power source. The energy required for the pump operation is derived from the potential energy of the incoming flow of water due to gravity. Hydraulic ram pumps use the momentum of a large amount of moving water and the water hammer effect to create high pressure, which is used to pump a much smaller amount of water uphill. Typically around 10 to 20% of the incoming water is delivered to the output. The simplicity of hydraulic ram pumps, which have very few moving parts, makes them economical to run and easy to maintain.
