Davey XJ90P Dynajet Pump with Pressure Switch

DYNAJET WITH PRESSURE SWITCH

Davey DynaJet pumps are a compact and economical, single stage jet assisted water pressure system, operated by a pressure switch, with an optional 40P base-mounted tank.

They are ideal for average sized residential homes with modern appliances right through to large double storey homes, pressure boosting applications and for water transfer.

These pumps are also great for domestic irrigation needs.

The DynaJet water pressure systems have been certified and tested to comply with the requirements of the AS/NZS 4020 standard.

The AS/NZS 4020 standard stipulates that products in contact with drinking water do not affect the taste or appearance of the water, do not support the growth of micro-organisms and do not release cytotoxic or mutagenic compounds or metals into the water.

Compact, all stainless steel horizontal multistage centrifugal pump pressure system control options to suit application. Flows to 430lpm and heads to 65m.

Applications

Average homes with modern appliances to large double storey homes

Installation & Priming

On installations with suction lifts over 1m a good quality foot valve or non-return valve should be fitted to the suction pipe.
The system is primed by filling the pump and suction line with water through the priming port and replacing priming plug prior to switching on.
