Applications: A Wallace MAXIPUMP OR HYDROJET automatic pressure system can supply house or garden.
MPEP3000, MPEP5000, HJ60, HJ100, OR HJ140 provide a constant pressure at a constant flow. HJ60PT OR
HJ100PT will provide varying pressure within a set pressure band.
MPEP3000, MPEP5000, HJ60PT, HJ100PT, HJ60, HJ100, OR HJ140 operate from above or below ground rain
water tanks, spear points or any other clean water source.
Suction lift capabilities of above pumps is as below provided they are installed to these instructions. MAXIPUMPS
5m; HYDROJETS 6m.
Operation of pumps with suction lifts of greater than – MAXIPUMPS 3m; HYDROJETS 4m – may significantly
reduce pump performance.
The MPEP3000, MPEP5000, HJ100, OR HJ140 are suitable to supply outlets up to max 15 metres vertically above
