Saudi Aramco Buy Hidrostal Pumps


Saudi Aramco, Ras Tanura Refinery, Industrial Wastewater Treatment Plant have placed a substantial order with Hidrostal (UK) Limited for three Hidrostal horizontal screw centrifugal 400 mm end suction pumps of stainless steel construction.

Each pump is driven by a 90 kW 8-pole motor and is to handle 7200 usgpm (454 lit/sec) of wastewater containing oil at a differential head of 42.2 ft (12.9m). The pumps are due for despatch in October 2003.

The Hidrostal pumps were selected primarily because of the unique low shear design of the Hidrostal screw centrifugal impeller which allows pumping with minimum agitation, an essential factor when wanting to avoid the formation of oil/water emulsions as required by Saudi Aramco.

Hidrostal are the inventors of the screw centrifugal impeller and are a company totally dedicated to its development and improvement. The continuous research and development programme has lead to a family of pumps being developed with variations of the screw impeller to solve specific pumping problems.
