Tsurumi Pumps

Submersible Corrosion-Resistant Pumps

If you are looking for a pump that can handle your chemical fluids of low pH values as well as sea water, look no further.  Tsurumi corrosion-resistant pumps use corrosion-resistant materials for all parts that are exposed to fluids, including the impeller, casing, motor frame, outer cover, strainer stand, bend, flange, and sealing parts.  This guarantees that any part of the pump that is exposed to fluids will stay in good condition to keep the pump running smoothly.

Tsurumi submersible pumps are made of 316 stainless steel casting.  In addition to this, the principal parts of the pump are made with this same stainless steel casting.  Because of this, reliability is improved drastically in comparison with stainless steel in applications involving heavy-duty work.  This allows Tsurumi’s pumps to serve in harsh environments such as mines and quarries, as well as in chemical plants and wastewater treatment plants.   As for the pumps geared for seawater application, Tsurumi uses titanium for the parts exposed to fluids.  The combination of resin and titanium enables a lightweight compact design that is the most suitable for handling seawater.

High Head Drainage Pumps

Tsurumi drainage pumps are submersible heavy-duty pumps specialized for high head.  They are available in a wide array of motor outputs/sizes.  These pumps have played an active role in various fields, from small/medium-scale civil engineering and construction work that requires high reliability, to large-scale projects for constructing tunnels, bridges, and dams.  And, because of the slim body of these pumps, they have been used to drain mine pits where there is a requirement to work in a limited amount of space.

To withstand the harsh environments, these pumps have impellers and mouth rings made out of high-chromium cast iron that provides wear resistance.  This pump is even equipped with seal pressure relief ports that release pump pressure applied to the mechanical seal.  To endure even extended operation at low water level, these pumps also feature flow-thru design that forcibly cools down the motor.  With these features, Tsurumi pumps provide excellent reliability and durability that enable continuous duty for long periods of time.
