QXV Internal Gear Pump

For pumping low-viscosity fluids

Smultistage pressure build-up

S250 bar can be developed at viscosities around

0,8 mm

2

/s [cSt]

Svolumetric efficiency up to 98%

Stemperatures up to 160°C

Ssuitable for ATEX compliant explosion protection

Ex II 3 G T3 and T4

Sused successfully to pump kerosene, diesel fuel, brake

fluids, Pentosin, HFA, …

Ssuitable for use with variable speed drivers

1General

of the application, up to five pump stages can be connected

in series. The unit is based on the well-known QX internal

gear pump, which is distinguished by its very low noise lev­

els and almost imperceptible pressure pulsations. The large

number of closely spaced sizes ensures that the right size

is always available for every application.

1.1Product description

The QXV internal gear pump is a special development for

low-viscosity fluids. By using several pump stages con­

nected in series, pressures to 250 bar can be developed

with high efficiency at viscosities of around 1 mm

2

/s . The

QXV is being used with great success to pump aviation jet

fuel, automotive fuels, paraffin oil/kerosene, brake fluids,

Pentosin and HFA fluids. Dependent on the requirements

1.2Application examples

STest rigs for diesel injection nozzles

STest rigs for testing Jet A1/fuel controllers for aircraft

turbines

SRolling mills

SFuel pumps for gasturbines

SWelding machines

SLubrication pump for spindle bearings

1.3ATEX compliant explosion protection

The internal gear pumps QXV are suitable for application in

hazardous areas and complies with the following guide­

1) Due to manufacturing tolerances, there may be slight variations in the displacement.

2)The lower the speed, the smaller the p/stage (linear relationship)

3)Second suction port is necessary for n  1200 rpm (see section 5.3 Special features)

4)Do not run up pump against pressures higher than 20 bar

5) For speeds > 1450 rpm, the inlet pressure of min. 0,95 bar absolute is required.
