carried out.
WATER SUPPLY CONNECTION
High speed pumps can be fed from mains water tap pressure
(POSITIVE PRESSURE) or draw from a tank or sump via suction
(NEGATIVE PRESSURE) however if used on suction (NEGATIVE
PRESSURE) for prolonged periods premature seal wear is likely to
result.
To run on either option please follow the instructions below:-
MAINS TAP PRESSURE (POSITIVE)
A clean water supply with a minimum of 15 Litres (3.3gallons) per
minute flow rate with a minimum pressure of 2 Bar (30psi) is
required. The inlet/supply hose should preferably have an internal
bore dimension of 19mm (3/4”) the minimum acceptable internal bore
dimension is 13mm (1/2”)
DRAWING FROM A TANK OR SUMP-SUCTION (NEGATIVE)
To use the machine to draw from a tank or sump the suction hose
assembly should be used. The suction hose has an internal bore
dimension of 19mm (3/4”) and should be as short as possible. The
“suction head “ should be kept to a minimum and in any event
should not exceed 610mm (2.0”) The water should be clean and the
tank/sump of sufficient capacity to prevent the pump running dry
whilst in use.
