New submersible pumps offered by the company include the 4-inch (100mm) Master H and 3-inch (75mm) Sandy N models made by Grindex.
Sandy N submersible pumps are designed to achieve a maximum head of 25m and maximum flow of 16 litres per second while Master H submersible pumps can achieve a maximum head of 58m with maximum flow of 30 litres per second.
Other models of heavy duty submersible pumps include the 3-inch (75mm) Minette and Salvador models.
The Minette water pump has a maximum 20m head and pumps up to 15 litres per second, while the Salvador has a maximum head of 14m and maximum capacity of 13 litres per second.
All submersible pumps are capable of handling abrasive solids and will operate continuously without supervision.
The Salvador range of submersible pumps is ideal for sludge and mud with high solids content.
These water pumps can deal comfortably with particle sizes up to the diameter of the pump inlet opening. They also work well with light slurry.
Two 3-inch (75mm) submersible pumps supplied by Kennards Hire were used on an unusual dewatering job during the construction of a luxury home on the edge of Sydney Harbour.
The excavation was made to a depth of five metres and also had grout injection water protection, yet some seawater still seeped in on a rising tide.
It was pumped up into a three-stage filtration system set up on ground level and then into a home swimming pool. After settling, the water was discharged into the stormwater system.
Kennards operates a network of ‘pump branches’ that offer specialised expertise in this field and also function as general hire centres.
