Screw Pump BT-IL
A screw pump BT-IL is a positive displacement pump handling lubricating fluids under fluctuating flow rates, pressure and viscosity without losing efficiency.
Pump design and construction enable silent fluid handling without turbulence. Therefore, the pumps operate at high rotational speeds with high reliability. The design of the screw pump also means that it can be used where suction capabilities are difficult, such as pumping over long distances, or where the pump is located above the liquid.
The self-priming screw pump BT-IL from Azcue Pump in Spain is used where larger quantities of fuel oils or lubricants are transferred. The screw pump is horizontal in design with inline suction and discharge, delivered flanged as standard.
Function of a Screw Pump
Azcue’s screw pump consists of three spindles surrounded by a pump casing.
The medium, f.inst. oil is transported axially through the pump via the chambers that arise between the casing and the spindles.
- Flow Rate up to 35 m³H
- Max Head (pressure) up tol 16 bar
- Outlet Sizes DN 50-100
- Max Temperature 160° C
All pumps are available in cast-iron

Approved Screw Pump
Each pump is designed to fit your process, resulting in greater efficiency and lower lifetime costs in terms of wear and energy consumption. All pumps are tested individually before leaving the factory. The screw spindle pump is type registered by Lloyds / ABS.
Like the other pumps in the Azcue program the screw spindle pump BT-IL benefits from interchangeable part for reduced on board stockholding. The task of replacing a pump prematurely that just needs maintenance won’t be necessary.
At West-Marine, we have many years of experience in servicing pumps from Azcue Pumps in Spain and guarantee supply of spare parts for many years to come from final production of a model. Thus, the user doesn’t need to replace a pump – only a spare part.
