Operating principle and construction

VD-150 is a positive displacement transfer pump working on the internal eccentric gear principle. The volume formed between the driven outer rotor and the freely rotating inner gear expands on the suction side to draw the fluid in and contracts on the discharge side to push it out. Flow is proportional to speed and independent of pressure. Efficiency rises with viscosity because internal slip decreases. The foot mounted casing carries the shaft in fluid lubricated plain bearings; the compact construction suits direct coupling to a standard motor.

Features

Bi-directional
reversing the motor swaps suction and discharge

Self-priming
suction lift up to 3 m at sea level

Low speed operation
pulsation-free, quiet transfer with low wear

Thermal oil heating jacket on casing and cover
option (code T)

Bearings lubricated by the pumped fluid
no separate lubrication circuit

Internals accessible by removing the cover; serviced without disturbing pipework or motor

Suction and discharge ports at 90° to each other
bottom inlet, side outlet

Frequently asked questions

Which liquids does VD-150 pump?

VD-150 pumps liquids from 10 to 55,000 cSt up to 230 °C. Applications: Bitumen, PMB, bitumen emulsion and oxidised bitumen transfer; Fuel oil service tanks — diesel, HFO, LFO; Thermal oil heating circuits; Resins, polymers and adhesives.

What is the maximum differential pressure of VD-150?

14 bar in the standard version.

How do I calculate the flow of VD-150?

Theoretical flow = displacement × speed. For VD-150, q = 5.556 l/rev. When viscosity increases, the permitted maximum speed decreases. Use the capacity table in the datasheet and our note on viscosity and speed to select the pump.

Is an ATEX version of VD-150 available?

Yes. The marking is II 1/2G Ex h IIB T4 Ga/Gb, zones 0 and 1. The maximum liquid temperature is 130 °C. Details: ATEX gear pump note.

Is VD-150 available with a heating jacket?

Yes. For liquids that become solid when cold, such as bitumen, the casing is heated. The options are in the technical table. Comparison: thermal oil or electric.
