The Azcue BT-MB Close Coupled Triple Screw Pump is the smallest screw pump in the Azcue range; a competitively priced model in the market for its pressure capabilities. 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-MB is ideal for the general transfer of fuels and lubrication oils under moderate performance conditions, the BT-HM is ideal for more demanding applications.

Thanks to its close coupled design, this horizontal self priming screw pump is compact in size for installations with limited space and has a top mounted suction and discharge. These Azcue pumps come complete with an integrated manually adjustable pressure relief valve.

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.

Features of the Azcue BT Series Screw Pump:

• Close coupled, self priming screw pump
• Pump manufactured in Spain
• Marine type approved by all classification societies
• Top mounted suction and discharge
• Compact horizontal design ideal for space saving installations
• Mechanical seal or magnetic coupling
• Integrated manually adjustable pressure relief valve
• Smaller footprint than an equivalent performing gear pump
• Low NPSH
• Suitable for lube and fuel oils 2-1500cSt
• ATEX version available upon request
• 230v, three phase 50Hz/60Hz motors available. IP55 as standard.

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 Azcue BT-MB triple screw pump is ideal for the following applications:
