Hot oil circulating pumps for feeding burners

As a supplier of thermal oil pumps for the last 15 years, Castle Pumps have probably dealt with a process just like yours before. We know that failing to select a pump capable of handling high temperatures conditions can result in seal failure and leaking. Therefore we have carefully selected a range of pumping solutions that can provide optimal performance and require minimal maintenance time. From high temperature oil pumps used to feed an oil burner or furnace to hot oil circulation pumps for circulating the fuel as part of a large, industrial boiler feed or system, we have a solution. Some of the most common heat transfer oils that we have supplied pumps for in the past include Marlotherm, Duratherm, Paratherm, Multitherm, Mobiltherm and Dowtherm.

Past thermal oil pump project

Castle Pumps’ technical sales engineers have been working with customers, providing high temperature oil transfer pump solutions for over 10 years.

Find out how in this past project we helped a UK based oil manufacturer with a pump for transferring furnace oil from tanks to vehicles at very high temperatures. We specified and delivered a suitable vane pump able of handling the oils up to 250°C with an ATEX motor within 4 weeks of the customer placing their order.
