TSURUMI’S UNIQUE FEATURES

A | Tsurumi Stuffing Box – absolutely watertight

The stuffing box is located at the cable entry section and takes the part of sealing off water. As the cable conductors consist of twisted wires, water may penetrate into the motor by the capillary phenomenon when cable sheath or insulation is damaged or when the end of the cable is submerged. The construction is such that a certain part of the insulation of each conductor is peeled and filled with rubber or epoxy resin for the complete sealing.

B | Built-in motor protection

Located directly above the motor windings, a snap-action self-resetting bi-metal device cuts off voltage from all three phase windings simultaneously if the current is too large in one, two or all three windings, or if the windings get too hot.

Tsurumi enables measurement of winding resistance and insulation from the far end of the cable, without ever removing the cover from the motor in the field.

C | Ball bearings of highest quality

Due to the high quality of the shaft and the bear rings all pumps can be run horizontally when entirely submerged.

D | Double mechanical SiC seal in oil bath

All Tsurumi pumps dispose of a double mechanical seal for increased durability:

The double inside mechanical seals of all our sewage pumps have sealing rings of Silicon Carbide, no other material has greater hardness. Resistance to temperature fluctuation and corrosion is also the best available.

E | Oil Lifter

A special guide vane is attached inside the oil chamber. With the motor rotation oil is pumped up. Therefore, even at low oil level lubrication and cooling of the mechanical seal is secured.

F | Impeller

A variety of types are available, depending on applications, i.e. open type, closed type, non-clog type and vortex type.

SEWAGE PUMP

Tsurumi designs a complete range of sewage pumps that provide transportation, aeration and decanting. Products are designed to suit wastewater plants of any size. Tsurumi equipment incorporates 90 years of innovation to deliver effective, long-lasting service to meet your needs.

Multipurpose

The strength and power of Tsurumi’s pumps mean they can transport a wide range of substances including sludge, slurry, contaminated water and sewage.

Durable

Tsurumi has a reputation for durable pumping equipment that stands the test of time. Some of its pumps can even be found working today after more than 20 years’ active service. Paramount to this unrivalled reliability is some special innovations – click here to learn more.

Easy maintenance

Tsurumi’s pumps are built to last. They are designed for easy maintenance and quick repair. Their simple yet robust construction means they can be dismantled using basic tools (a screwdriver or spanner) and technicians need only basic training to handle maintenance.

Sewage Treatment

A considerable experience of Tsurumi’s long lasting designing concept in products for water transfer widened a range of products for treating waste water.These special and unique Tsurumi products can be used not only in the physical or biological steps of waste water purification but also in other applications.

Tsurumi being a one-stop-shop for all your needs in industrial and municipal waste water treatment plants.

Bar screens

The Tsurumi bar screens are used to remove particles in the first step of waste water purification. Tsurumi bar screens are a durable and efficient solution for primary fine treatment of wastewater and are available in several rake distances for different sizes of particles.

Agitator pumps

The Tsurumi KRS-range agitator pumps have proofed to be a reliable solution when it comes to removing sediment from sand-traps. Since it has been originally designed for tough applications in the construction sector, the KRS can efficiently handle a medium with a high content of sand or sludge.

Scum skimmers

The Tsurumi FSP submersible scum skimmer incorporates a jet injector (suction mechanism) for collecting scum efficiently. Floating impurities can be removed easily.

Aerators

The Tsurumi aerators are fast and cheap to install, providing an aeration effect as well as a mixing effect in the sewage water. They can be installed in any basins and do not require a compressor. Tsurumi aerators feature a unique Air-Seal-Principle that ensures the Double Mechanical Seal never comes into contact with the liquid during operation. This, along with several other innovations, improves the overall reliability of the product.

TSURUMI DRAINAGE PUMPS

Tsurumi has a huge variety of robust and powerful pumps to suit even the most demanding of construction projects. We can provide the pumping solution your project needs.

Multipurpose

Over the years, Tsurumi pumps have been used in construction sites from tunnels and bridges to buildings and stadiums. Strength and power mean they can transport a wide range of substances including contaminated water, slurry, mud, bentonite, cement, corrosive liquids, etc. – almost anything.

Durable

Sticking to schedule on a construction site is crucial. Equipment cannot let you down. Tsurumi’s long history has helped develop products with unrivalled reliability. Some of its pumps can even be found working today after more than 20 years’ active service. This strength comes courtesy of a number of special features – click here to learn more.

Easy maintenance

Tsurumi’s pumps are built to last. They are designed for easy maintenance and quick repair. Their simple yet robust construction means they can be dismantled using basic tools (a screwdriver or spanner) and technicians need only basic training to handle maintenance.

Power

Pumps can reach heads of up to 177 m and have capacities of up to 12,500 l/min, with motor sizes ranging from 0.4 kW to 110 kW.

Residue

Removing residual water is essential to maintaining a safe construction site. Tsurumi’s residual dewatering pumps can empty large areas of water, reducing levels down to as little as 1 mm. In fact, the company’s LSC series is affectionately known as ‘The Puddle Suckers’ for their unrivalled abilities.

Heavy-duty cable

A ruptured pump cable is the most common cause of pump failure. Tsurumi offers a heavy-duty pump cable for its pumps that can withstand high mechanical stress and has a tensile strength of 15 N/mm².

Pressure

The Tsurumi name is synonymous with strength. Its endurance pumps can withstand very high pressure found in deep water
