Tapflo is pleased to offer the Helical External Gear Pump Range by Yildiz for medium and high-pressure transfer applications. Lubrication pumps, fluid power transfer units, and oil pumps in engines are all common applications.

The Helical Gear Pump Range has a compact robust design with many beneficial features including:

Shaft support on both sides of the gears
Pressures up to 30 bar
Wide speed range, up to 50-1500 rpm
Often used as lubrication pumps in machine tools, in fluid power transfer units, and as oil pumps in engines.
Precise transfer and metering applications involving polymers, fuels, and chemical additives.
Can be fitted with Heating Jackets to maintain fluid temperature
By Pass/ Pressure Relief Valve can be installed to protect the pump from over-pressurisation

How does a Helical External Gear Pump work?

The pump features a horizontal shaft, 180° port position and has 2 external helical gears.

The pump shaft operates, moving the gears which draws liquid into the port. The liquid fills the space between the gears and moves towards the outlet of the pump as the shafts turn.

Applications

The Helical External Gear Pump is ideal predominantly for industrial applications such as:

Petroleum
Fuel
High volume transfer

It is also suitable for transferring molasses.
