IMPORTANT: READ THIS MANUAL BEFORE INSTALLING OR
OPERATING THE PUMP.
SAFETY: Carefully read these safety messages.
CAUTION: Review instructions before operating.
APPLICATION
These pumps may be direct-coupled or belt driven from a suitable power
source - electric motor, gas engine, etc. They are intended for installa-
tions where the vertical distance from the pump to water surface does
not exceed 7.5m (25 ft.). In all installations, friction losses in the piping
must be taken into consideration.

Complete pressure and flow data is available in the Product Specification Sheets and Performance Curve section.
(a) LOCATION: The pump should be installed in a location that
provides adequate drainage, room for servicing, and protection
from freezing. A proper foundation is necessary to maintain the
alignment between pump and power source. To reduce friction
losses and provide maximum capacities, the location of the pump
should be such that a minimum of suction piping is required.
(b) SUCTION PIPE: It is recommended that only new, clean pipe
or hose be used and the size be the same as the pump suction
tapping. If the pump is installed any appreciable distance away
from the source of water supply, the suction pipe should be
increased by one size. The suction pipe must always slope
upwards from the water source to the pump to avoid air pockets in
the line. In cases where the pump has to be reprimed often,and it
is not necessary that a lot of water be delivered, it is advisable to
use a 90° or 45° elbow on the suction line. This enables the pump
to prime sooner and also prevents kinking of the hose. In cases
where a maximum volume of water is required over a prolonged
period of time, the suction line should be led almost horizontally
to the pump. Non-toxic thread compound should be used on all
pipe joints and connections should be thoroughly tightened. A foot
valve should be connected to the bottom end of the suction pipe
and must be submerged at all times.
(c) FOUNDATION: A rigid mounting system must be provided for
the pumps to ensure that correct alignment of the drive coupling
can be maintained. It is recommended that a mounting frame
be constructed from heavy steel channel and both the pump
transmission and the power source be bolted to this. If possible,
the frame itself should be securely anchored to a rigid concrete
foundation.
(d) ALIGNMENT: Proper alignment is essential for proper pump
performance and satisfactory life of transmission drive
components. For direct couplings, ensure that shafts are both
parallel and concentric. The units will be concentrically aligned

INSTALLATION
when a straight edge rests evenly on both halves of the coupling
in all positions. The shafts will be parallel when the gap between
the two halves of the coupling is even at all positions around the
coupling.
(e) ROTATION: Ensure that shaft rotation will be in the same direction as
the arrow on the casing (clockwise, looking from shaft end).
(f)
SPEED: Pressure and Flow Data is available for transmission
speeds ranging from 1750 to 3450 RPM. Operation at speeds
outside this range is not recommended.
