5 Operating Conditions

Ambient requirements: LORENTZ PSk2 submersible and
surface pump systems can be operated up to 3000 me-
ters/10 000 ft above sea level and at an ambient air temper-
ature of up to 50 °C/122 °F. The PSk2 controller is designed
for use in environments classified as pollution degree 3 in
accordance with IEC 60-664-1: Conductive pollution occurs,
or dry non-conductive pollution, which becomes conductive
due to condensation, is to be expected.
Fluid: LORENTZ PSk2 submersible and PSk2 CS-F/CS-G sur-
face pumps can be used for drinking water supply, livestock
watering and irrigation applications not containing solid or
long fibred particles larger than sand grains, with a max.
grain size of 2 mm. The max. permitted sand content for
submersible pumps is 500 ppm, for surface pumps 50 ppm.
A higher sand content will reduce the pump life considerably
due to wear. The max. salt content is 300-500 ppm at max.
30 °C / 86 °F. Defects due to pumping other liquids are not
covered by the warranty.
Fluid temperature: Depending on the type of your
LORENTZ pump system, different requirements for fluid
temperatures apply:
PSk2 submersible pumps- The maximum fluid tempera-
ture for PSk2 submersible pumps is +30 °C (86 °F).
PSk2 surface pumps - The maximum fluid temperature
for PSK2 CS-F surface pumps is +70 °C (158 °F), for PSk2
CS-G surface pumps +90 °C (194 °F).
Humidity: The pump system must not be stored or operat-
ed where the average day humidity is above 80 %.
For PSk2 surface pumps:
Pump location and air salinity: The pump should be
sited in a well-ventilated and frostfree position. The distance
between the pump unit and other objects should be at least
150 mm / 6" to ensure proper air circulation. If installed
outside, the pump must be protected from rain and direct
sunlight. This will increase the durability of the pump. It
should not be stored or operated within 1 km / 0.6 miles of
coastal regions or in saline air (more than 2 μg/m³).
