Tsurumi pump grinds costs

Tsurumi grinder pumps offer cost savings over conventional pumps because they reduce the size of the solids passed using a ‘grinder’ process. Although this is not a radical new technology, the new Tsurumi grinders offer users significant advantages, promises Aussie Pumps.

“Those features translate into real benefits for applications as diverse as food processing, livestock waste and even small packaged sewerage stations,” said product manager Bob Massiah.

Tsurumi has developed its MG series of grinder pumps for efficient handling of solids. The pumps grind solids passing through into small pieces. This ensures the waste travels through the pump thus enabling the use of narrow discharge pipes.

“Tsurumi’s breakthrough grinder design enables solids to be transferred through cost effective 1 ½” & 2” pipes, and at high pressures. This means the pumps deliver higher heads for moving wastewater further distances,” said Massiah. “Grinding the solids smaller also means the waste breaks down faster and more efficiently.”

Tsurumi opted to use high chromium iron for the grinder mechanism over stainless steel for its abrasion resistance and the company reports that users say the new MG series pumps outlast other grinder pumps.

The three- phase, two- pole, cast iron pumps are available with 32mm and 50mm discharge ports. The 50mm pump has a maximum head of 35 metres (50 psi) and a capacity of up to 320 lpm.

Tsurumi developed special high torque, two- pole motors for these pumps that can start up even when the pump chamber is filled with solid- laden liquid.

Tsurumi’s MG series can be mounted on guide rails. This makes it simple to remove the pumps for maintenance and service. An adaptor plate is available to enable swap out of other brands without the need to replace the existing guide rails or ductfoot elbows.

Like all Tsurumi submersible pumps, the MG series include features that extend the life and enhance reliability of the pump.

Significant design details make a big difference. They include an anti-wicking cable entry that prevents water from entering the motor if the power lead is damaged or the end of the cable is accidentally submerged.

A silicon carbide seal is standard on all models. All seal surfaces are submerged in an oil chamber, away from the pumped liquid. This ensures lubrication and protects against ingress of foreign materials.

The oil bath features a patented ‘Oil Lifter’ that increases mech seal longevity. The lif ter ensures both the upper and lower seals are lubricated and cooled, even if the oil level in the chamber is low.

“Tsurumi is the only company we know of that will offer a three-year warranty on submersible sewage pumps,” said Massiah.
