Operating principle and construction

VN-863 DN80 is a positive displacement transfer pump working on the external helical gear principle. Two helical gears in mesh carry the fluid along the casing wall from the suction to the discharge side; the continuous, overlapping tooth engagement gives a smooth, pulsation-free flow. The compact casing runs at up to 950 rpm and is driven directly by a 6-pole motor without a gearbox, which gives a high flow from a small envelope at low cost. Flow is proportional to speed and independent of pressure.

Features

Direct drive with a 6-pole IEC motor
no gearbox, low cost, few parts

Helical tooth engagement
pulsation-free, quiet flow

Bi-directional
reversing the motor swaps suction and discharge

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

Thermal oil heating jacket on casing and cover
standard; electric heating (code E) as option

Integrated by-pass valve on the cover
standard

Bearings lubricated by the pumped fluid
no separate lubrication circuit

Suction and discharge ports opposed
the pump goes straight into the line

Frequently asked questions

Which liquids does VN-863 DN80 pump?

VN-863 DN80 pumps liquids from 10 to 5,500 cSt up to 230 °C. Applications: Diesel, gas oil and light fuel oil transfer; Lube oil, hydraulic oil and grease circuits; Thermal oil circulation; Solvents, thinners, paints and varnishes.

What is the maximum differential pressure of VN-863 DN80?

15 bar in the standard version.

How do I calculate the flow of VN-863 DN80?

Theoretical flow = displacement × speed. For VN-863 DN80, q = 0.863 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 VN-863 DN80 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 VN-863 DN80 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.
