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

Tsurumi-NH-Modular

Applications

• 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.

Accessories

• Duckfoot Bend
• Guide Support
• Guide Hook
• Lifting Chain 5m (with Shackles)
• JIS 10kg/cm2 Flange

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

 

 

Design

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.

 

 

 

 

 

 

 

 

 

Applications

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.

Function

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).

Horizontal, radially split volute casing pump in closecoupled design, single-stage, single-entry, available with various impeller types: non-clogging impeller and free-flow impeller.

The hydraulic system and the motor are firmly connected and form a close-coupled
unit. Impeller (7) and motor (10) are arranged on a common shaft (5)

KSB-KWP-Curves

Applications

Handling of pre-treated sewage, waste water, all types of slurries without stringy substances and pulps up to 5 % bone dry with a maximum density of 1.1 kg/dm3.

 

 

 

 

Function

The steadily rotating impeller (7) of the centrifugal pump transfers mechanical
energy to the fluid passing through.

KSB-KWP-Bloc-ModularThe fluid enters the pump axially via a suction nozzle (6) and is accelerated outward
in a cylindrical flow by the rotating impeller (7). The flow profile of the pump casing
converts the kinetic energy of the fluid into pressure energy. The fluid leaves the
pump via the discharge nozzle (2).
The casing is fitted with a replaceable wear plate (1). The diagonal clearance gap
prevents frequent deviation of the flow in the clearance gap heading in the direction
of the suction nozzle. This ensures a longer service life if solids-laden fluids are
handled.
The casing is closed by a discharge cover (3). The shaft (5) enters the casing via this
discharge cover. A shaft seal (8) provides reliable sealing towards the atmosphere.
The shaft is supported by oil-lubricated rolling element bearings (9). The motor (10) is
connected to the casing via an intermediate lantern (4)
