DIP 25, 35, 65

Overview

To reduce the risk of serious injury or death to
yourself or others, read the Safety instructions
section found on the previous pages of this
manual before operating the machine.

Design and function

DIP 25, DIP 35 and DIP 65 centrifugal pumps are
intended for pumping relatively clean liquids, such
as water and coolants. It is not recommended to
pump any liquid with a temperature above 100°C
(212°F). Do not pump abrasive or flammable liquids.
No other use is permitted. DIP 25, DIP 35 and DIP
65 are adapted to meet different demands in respect
of flow(Q) and pressure head(H) (see diagram
below).
DIP pumps are submersible, which means that they
can work fully submersed in the pumped medium.
The impeller is die cast in stainless steel, and is
driven by an air motor. The compressed air flows
through an air-filter which stops any foreign matter
in the compressed air from entering the pump. A
governor limits the maximum idling speed to 6000
rpm. Between the pump section and air motor section
is a mechanical seal which receives lubrication from
the oil in the exhaust air. When the pressure rises,
the pressure between the sealing surfaces in the
mechanical seal will also rise. The pumps are self
priming.
The diagram is valid at 6 bar (87 psi) and when
pumping from base plate level. Use of a suction hose
is not supported.

Safety and operating instructions
NOTICE The capacity of the pump will change and
the chart above will not be accurate if a lower air
pressure than the recommended is used, or if the
pumped liquid has a different viscosity than water.
