Tsurumi Pump - Submersible NH

Tsurumi-NH-series is a cast iron made, submersible wastewater pump utilizing 2-pole
motor. This impeller is a shrouded two-channel impeller. Each channel is
designed to have a larger area and it enables the pump to be suitable for
pumping wastewater containing a certain size of solids. The pumps are available in six
motor sizes ranging from 1.5 to 7.5kW and available in either High-Head or High-Volume Type


• Draining wastewater from kitchen at a hotel, restaurant, and
hospital, etc.
• Drainage from factory,


car park, and basement, etc.
• High-head pumping of wastewater containing solid matters


1. Anti-wicking Cable Entry

An anti-wicking block is provided at the cable entry
Tsurumi-NH-Cablesection of the motor chamber. Even if the cable jacket
becomes damaged or the tip of the cable is accidentally
immersed in water, this device prevents water from traveling
into the motor chamber through capillary action.

2. Motor Protector

A built-in thermal motor protection device reacts to the excessive heat
caused by overcurrent or run-dry conditions. It not only cuts off the
motor circuit automatically but also resets by itself. When the motor
cools down to a safe operating temperature, the motor restarts

3. Dual Inside Mechanical Seal

A mechanical seal with dual seal faces containing silicon carbide (SiC)
is equipped with the oil chamber. As both upper and lower sealing
faces are lubricated by the oil only, it ensures a longer life of the
product and a stable sealing effect.

4. Oil Lifter (Patented)

Tsurumi-NH-OilThe Oil Lifter is a lubricating device that forcibly lubricates the mechanical
seal. It further stabilizes the functions of the mechanical seal and
extends the life expectancy of the seal and also the maintenance term.

5. Air Release Valve

In order to prevent “air lock”, an air release valve is built in the pump
casing. The valve is similar to a ball check valve. When air goes
through the valve, the ball stays at the bottom, but when the pumped
water starts to flow, it closes the outlet by its buoyancy.

6. Seal Pressure Relief Port (5.5 & 7.5kW only)

A small chamber is provided between the oil seal and the shaft hole of
the pump casing, and this chamber is led to the outside by this hole.
With this device, the pumping pressure does not act on the mechanical
seal. The mechanical seal is protected from over rated limit.


Guide Rail Fitting System

The guide rail fitting system connects the pump to and
Tsurumi-NH-Guide railfrom the piping easily just by lowering and hoisting the
pump, allowing easy maintenance and inspection without
the need to enter the sump.
The TOS is the standard guide rail fitting system made of
cast iron and is compatible with cast iron pumps.

KSB Pumps - Innovation of the year 2014 for High Efficiency

Innovation of the year 2014

Magnochem mag-drive pump – great performance.

High output per size meets maximum efficiency: 2014 saw KSB pumps add a new mag-drive pump to its range with the next-generation Magnochem. The standardised chemical pump is optimised to meet the requirements of the food, oil and chemical industries. The innovative type series includes 52 hydraulic sizes and numerous magnetic coupling variants. The KSB pumps are in compliance with DIN EN ISO 2858 / ISO 5199 and are particularly energy-efficient.

Mag-drive pumps are often the first choice for applications requiring the transportation of hazardous, odour-intensive, hot or solids-containing fluids. The new Magnochem mag-drive pump from KSB unites a whole host of innovations: alongside the magnetic coupling’s flexible modular design system and four operating modes, the central positioning of the plain bearings with thrust bearings arranged internally represents a unique aspect of the design which ensures maximum operating reliability. Magnochem can also reliably handle low-boiling fluids such as ammoniac or hydrocarbons. If required, an auxiliary impeller can increase pressure in the critical range and prevent the fluid handled from evaporating.

Optimally suited to all fluids handled by KSB pumps

KSB’s engineers paid special attention to the magnetic coupling design and the routing of the circulation, cooling and lubricating flows. Magnochem’s four operating modes range from basic internal circulation to the so-called “dead-end configuration” with heat exchanger and auxiliary impeller. This allows the pumps to be optimised for the transportation of polymerising, coagulating, crystallising or easily evaporating substances at any time.

Highly durable materials such as titanium or zircon oxide

KSB Pumps As well as corrosion-resistant materials such as the nickel alloy Hastelloy or titanium, zircon oxide can be used for Magnochem containment shrouds as required. This ceramic material:

  • Is highly resistant to corrosion
  • Does not generate eddy currents when exposed to a moving magnetic field
  • Prevents heat losses which reduce the pump’s performance

The magnetic material selected by KSB’s engineers is samarium cobalt, which is extremely temperature-resistant and offers excellent magnetic properties.

The right magnetic coupling for every size

As a rule, KSB can offer multiple coupling sizes for every pump size. This allows the pump’s magnetic drive to be tailored to the performance required. Static and dynamic balancing of the rotor during manufacture ensures that Magnochem pumps experience very little vibration when in operation.

Plain bearings require a film of fluid for lubrication in order to keep friction and associated heat to a minimum and to cool the bearing. An optional leakage barrier provides extra reliability and protects the motor, the robust rolling element bearings and the environment against any fluids which might escape. The space around the impeller is monitored by sensors which ensure that leakage is promptly registered.

KSB pumps Also available in close-coupled design

As well as the conventional models in back pull-out design, a close-coupled KSB Magnochem model with 44 sizes is available for spatially restricted installation locations. The type series’s highest flow rate is 1400 m3/h, at a maximum head of 233 m. The pump’s permissible operating temperature ranges from -90 °C to +300 °C.

Save Energy - Grundfos Pumps

The best opportunity to save energy is with pumps

It comes as a surprise to a lot of people that pumps currently consume 10% of global electricity. However, Save Energy – Grundfos Pumps and pumps also have the potential to save a lot of electrical energy. Pumps actually represent one of the best opportunities to reduce CO2 emissions using existing technology. This is because most pump installations are needlessly inefficient. Now is the time to change that Save Energy with Grundfos Pumps.
If everyone switches to high efficiency pump systems we can reduce 4% of the world’s total electricity consumption NOW.

It is time to Meet the Energy Challenge NOW, and Save Energy – Grundfos Pumps Now.

The Grundfos Blueflux® technology label for Save Energy – Grundfos Pumps

Without precisely the right motor and variable frequency drives (VFD), even the best pump will consistently waste energy. To facilitate simple selection of a high-efficiency pump solution, Grundfos has developed a technology label for the top of the line motor and drives range.

And with Grundfos high efficiency pump motor technology we can reduce the average pump’s electrical energy consumption by up to 60%.
