4.4 Pump

The pump is a non-self-priming, single-stage Grundfos HSEF
standard pump with volute casing. It has an radial suction port
and a radial discharge port with ANSI B 16.5 compliant flanges.
For technical data see page 24 chapter 15.3.1 Permissible flange
forces and flange torques.
The impeller diameter can be reduced to customise the pump
performance to a certain duty point. This means that the actual
impeller diameter differs from the standard diameter stated in
sales catalogues, data sheets, etc. The actual impeller diameter
is stated on the pump nameplate.
The HSEF pump is equipped with a stuffing box seal.

4.5 Engine

The pumps are driven by a stationary 4-stroke diesel engine from
John Deere or Doosan which has been specially adjusted to the
pump drive requirements of Clarke UK Ltd.
The rated engine power is adapted to the power requirement of
the pumps. The adjustment is made via the engine speed and
consequently this must not be changed. See appendix page 27
and section 1. Dimensions and weights for relationship between
the diesel engines and the individual pumps. Depending on
performance, the engines have a turbocharger and, if necessary,
also a charge air cooler.
The fuel injection pump has been set from factory,
Caution
and the setting must not be changed.
The engine is cooled via a heat exchanger in the water-cooled
John Deere and Doosan engines. The coolant is led to the heat
exchanger via a pipe connected to the discharge port of the
pump.
