Operation
7.1
Temperature
The pump will heat up during normal operation. Heat is generated as the pump hose is compressed
and released. The heat is removed by the lubricant and transported to the pump housing and cover.
This will result in a temperature higher than the ambient temperature.
WARNING
Avoid contact with the casing and cover under conditions of high pressure
and running speed.
7.2
Power rating
The pump requires a certain amount of power for the specified operating condition(s). The gearbox
and motor are sized to deliver that power at the given revolution speeds.

Refer to "Performance graphs" below to determine the required power.
WARNING
Overloading the motor can lead to serious motor damage. Do not exceed
the maximum power rating of the motor.
WARNING
Overloading the gearbox leads to increased tooth wear and shortened
bearing life. This can lead to serious gearbox damage. Do not exceed the
maximum power rating of the gearbox.
7.3
Performance graphs
The pump operating window can be found in the performance graphs in which discharge-pressure
curves are displayed in a speed-power diagram.
The pump and hose are designed to handle a discharge pressure up to 1600 kPa.The triangular area
between the 500 kPa and the 1600 kPa lines describes the allowed performance area. The required
duty points have to fall within this area. For discharge pressures lower than 500 kPa use the 500 kPa
line.
In the direction of higher speeds and powers, pump operation is limited by the heat generated, the
product temperature and the ambient temperature. Product temperature lines determine a
distinction between areas of continuous operation and intermittent operation in the graphs. The
graphs apply for a maximum ambient temperature of 45 °C.
If the duty for an application is specified in the area of intermittent operation, let the pump stand still
to cool down for at least one hour after three hours of operation.
