The Azcue BT-HM Spacer Coupled Triple Screw Pump is the most commonly specified screw pump in the Azcue range thanks to its robust construction and higher pressure capabilities than the BT-MB whilst still being cost effective. As a positive displacement pump, screw pumps are able to handle lubricating fluids under fluctuating flow rates, pressures and viscosities without losing efficiency. The Azcue BT-HM is therefore ideal for the transfer of fuels and lubrication oils under a range of performance requirements.

These self priming screw pumps have a spacer coupling for maintenance of the pump without having to remove the motor first and an additional ball bearing between the pump and motor to share the strain of operation, making it ideal for more heavy duty, continuous use. The nature of the screw pump design means it can be used where suction capabilities are difficult such as pumping over long distances or where the pump is located above the fluid

This self priming triple screw pump is horizontal and compact in size for installations with limited space and has a top mounted suction and discharge. These Aczue pumps can be supplied upon request with a magnetic coupling, which eliminates the issue of a mechanical seal leaking and therefore increases service life for vital applications.

Bulk Lube Offloading System for Mining Machinery - Screw & AOD Pumps

Castle Pumps are a "one stop shop" for pumping solutions, priding ourselves on being able to fulfil the customer's complete enquiry. This case study is an example of where we have ensured that the client only requires one point of contact for their pumping requirements. A mining company contacted us with an enquiry for both air operated and electrically driven lube oil pumps, which we were able to specify and supply.

The BT-HM Spacer Coupled Screw Pump is manufactured by Azcue Pumps. As the official UK Agent of Azcue Pumps, Castle Pumps are a leading Bombas Azcue supplier in the UK with unrivalled technical knowledge. Azcue Pumps are a European manufacturer with over 100 years’ experience in type approved pumps for marine and offshore applications. Today their pumps are installed in more than 10,000 vessel builds. Whilst originally developed for the marine market, Azcue Pumps’ reliability in applications that depend upon the safety and operation of a ship saw them become a desirable product in industrial applications involving water, fuels and lubricants.

One of the key benefits of the BT-HM triple screw pump like the other models in the Azcue range, is that is benefits from interchangeable parts for reduced on board stockholding. We guarantee supply of spares for 15 years from model discontinuation for long term pump servicing, saving the user from having to prematurely replace a pump that just needs maintenance.

Azcue BT-HM pump are cast, machined and assembled at their foundry in Spain. Each pump is manufactured to order and designed to fit your process, resulting in greater efficiency and lower overall lifetime cost in terms of wear and energy consumption. Before leaving the factory, pumps are individually tested to confirm performance meets the requirements set out in your enquiry.

The viscosity of lubricating fluids such as fuels and oils can change with a change in the temperature, unlike fluids such as water. Whereas a centrifugal pump’s performance is affected by fluctuations in the viscosity of the fluid, screw pumps operate just as efficiently. For that reason, the BT-HM triple screw pump is ideal for the following applications:
