4. Product introduction

4.1 JPA JPC

JPA and JPC pumps are horizontal, self-priming
centrifugal pumps.
JPA pumps are made of cast iron, and the JPC
pumps are made of a composite material.
The pumps are designed for pumping water and
other thin, non-aggressive and non-explosive liquids,
not containing solid particles or fibres.
The pumps are especially suited for use in
small-scale agriculture and gardening.
The pumps can be permanently connected to the
water mains or connected to a hose set.

4.2 JPA PM, JPC PM, JPA PT, JPC PT

JPA PM and JPC PM are compact boosters
consisting of a JPA pump and a Grundfos Pressure
Manager (PM 1 version). To reduce the number of
starts and stops, an external tank can be installed.
JPA PT and JPC PT are boosters consisting of a
pump, a pressure switch, a pressure gauge and a
diaphragm tank. The pressure switch automatically
starts the pump according to demand. The
diaphragm tank ensures a constant water pressure
in the water supply.

suction lifts up to 27 m. The pump body is made of
cast iron. The high suction lift is achieved by means
of an ejector which can be inserted into wells with a
diameter of down to 10 cm (4"). The boosters are
especially suited for use in small-scale agriculture
and water supply to farmhouses.
