WIKA Operating Instructions Hand Spindle Pump

Hand Spindle Pump

CPP1000-M/-L

At higher pressures a longer waiting time before stable operating conditions are

reached is to be expected than at lower pressures.

NEVER open the shut-o valve suddenly while the system is

pressurised. The valve may be opened only if the spindle has

been fully unscrewed in an anticlockwise direction.

(Exception: chapter 3.1.4 Venting the system)

■

Turn the spindle pump anticlockwise as far as the end-stop to vent the system

completely and only then open the shut-o valve.

■

You can now change the test specimen (and/or the reference instrument).

3.3 Handling the CPP1000-M/-L with shut-o valve for test connection

When calibrating instruments with large volume a shut-o valve for the test connec-

tions is a useful accessory (see chapter 9. Accessories). This shut-o valve makes

it possible to draw pressure medium from the reservoir into the pump and into the

connected test gauges. So it is not necessary to ll pressure medium into the test

specimen or the reference instrument before connecting to the pump.

For devices under test and reference instruments with a large

volume we recommend a shut-o valve on each test connec-

tion. When a ne adjustment valve (available as standard with

CPP1000-L) is used, only one shut-o valve can be mounted for the

test connection.
