Tsurumi-NH-Submersible Wastewater Pumps



Tsurumi-NH-Submersible Wastewater Pumps

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, underground 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.

Grundfos - SQ Ground water supply-private housing, small waterworks, small irrigation systems




Grundfos-sq-sqeThe Grundfos SQ 3″ submersible pumps offer a wide performance range, making it easy to find a model that will suit your individual requirements.

The Grundfos SQ is a compact, 3″ multistage centrifugal pump that can be installed in a borehole no larger than the pump itself. With their built-in electronics, SQ pumps are very easy to install and operate. They guarantee a reliable water supply at all times.

Equipped with permanent magnet motors, these flexible and compact pumps offer excellent efficiency levels and will supply pump heads up to 200 m.

If the SQ pump is connected to the Grundfos CU 301 control box, it enables the creation of a constant pressure water supply.





SQ/SQE pumps are suitable for both continuous and intermittent operation for a variety of applications:

  • Ground water supply – private housing, small waterworks, small irrigation systems
  • Liquid transfer in tanks
  • grundfos_sqe_320Pressure boosting
  • Environmental applications – remedial pumping or sampling
  • Garages and petrol stations.







Features and benefits

KSB Amacan K - Submersible motor pump with non-clogging impeller




KSB-Amacan K-ModularKSB Amacan K – Wet-installed submersible motor pump with non-clogging impeller, singlestage, single-entry, for installation in discharge tubes, explosion protection to ATEX II G2 T3.











Handling of pre-cleaned, chemically neutral waste water, industrial effluents and sewage, fluids not containing any stringy substances pre-treated by screens and sills, as waste water, mixed water and activated sludge pump in effluent treatment plants, irrigation and drainage pumping systems.


KSB-Amacan K-instThe fluid enters the pump axially via the inlet of the pump casing (1) and is
accelerated outward in a radial flow by the rotating impeller (2). The required energy
is transmitted from the electric motor (7) to the impeller (2) via the shaft (4). In the
pump casing (11) the kinetic energy of the fluid is converted into pressure energy.
The rotational movement diverts the fluid flow in axial direction. The casing wear
ring (12) prevents any fluid from flowing back from the casing into the inlet of the
pump casing. At the rear side of the impeller, the shaft enters the casing via the
discharge cover (3). The shaft passage through the discharge cover is sealed towards
the fluid by a shaft seal (10). The shaft runs in rolling element bearings (5 and 8),
which are supported by a bearing housing (9) and a bearing bracket (6).

Wilo Emu 6″ Submersible pump in sectional construction



Submersible-motor pump for vertical or horizontal installation.



Multistage submersible-motor pump with radial hydraulics. Housing parts made of NiAl‐Bz, impellers made of Noryl. Pressure connection as threaded connection, with integrated non-return valve.



Three-phase motor for direct and star-delta start Sealed, hermetically cast motor with enamel-insulated winding, resin-impregnated (NU 4…, NU 5…) or rewindable motor with PVC‐insulated winding (NU 611). Motor shroud made of stainless steel, A2/A4 quality.

Pump connection as standard NEMA connection. Sealing of motor shaft achieved through the use of a rotary shaft seal (NU 4…) or mechanical seal made of solid silicon carbide material.

Self-lubricating motor bearing. Motors in the NU 4…- and NU 5… series are filled with a water‐glycol mixture, motors in the NU 611 series are filled with a water-glycerine mixture. Alternatively, NU 611… series motors can be filled with potable water (T‐version). Frequency converter operation is permitted (SF 1.1).



The motor is cooled by the fluid. The motor must always be operated in submerged state. The limit values for the max. fluid temperature and the minimum flow rate must not be exceeded. Vertical installation is possible optionally with or without cooling jacket. For horizontal installation, bearing brackets must be used for reinforcement of the unit.
