Installation
Page 9
When a dealer or an owner installs a pump,
the following guidelines must be met:
1. The suction hose from the tank to the pump
must be equal to, or greater than the outside
diameter of the pump inlet connector (7).
2. The pump suction hose should be wire
reinforced to prevent collapse and firmly hose-
clamped at the connection.
3. The suction line from the tank to the pump
should be kept as short as possible and must
have a minimum of bends.
4. A suction filter must be fitted between the
tank and the pump.
5. The filter strainer should be approximately
50 mesh. The minimum filter area should be
250cm
2
per 100 l/min rated delivery of the
pump. eg. BP60/20 has a rated delivery of
58.2 l/min therefore the minimum filter area
would be 250/100 x 58.2 =145.5cm
2
.
6. The suction hose between the tank and the
filter should have a shutoff valve installed, to
allow the strainer to be cleaned without
emptying the tank. The parts of this valve
must not be smaller than the OD of the pump
inlet connector.
7. The maximum suction lift should be no
more than 1m for continuous operation and
3m for a maximum of 5 min during tank
filling.
8. Do not connect pump suction to mains feed, the
maximum inlet pressure is 1m (1.5psi)
Continuous Use
