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

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.

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

Grundfos-Unilift CC - Submersible drainage pump

 

 

Overview

Grundfos-Unilift CC-modularThe Unilift CC is a single-stage submersible drainage pump, designed for the pumping of drain water and grey wastewater. The Unilift CC can pump down to a water level of 3 mm above the floor by removing the strainer. The Unilift CC is suitable for permanent as well as temporary installation. The Unilift CC is fitted with a non-return flap valve in the outlet in order to prevent backflow from the piping system. An adaptor ensures good connections to 3/4”, 1” or 1 1/4” outlets.

The strainer is made of stainless steel, while the main pump parts, e.g. the sleeve and pump housing, are made of moulded composite materials.

The Multibox B-CC7 is an Unilift CC combined with further elements such as a hose with Storz coupling, an adaptor for threaded Storz coupling and a box with perforated-mesh sides to be used as a pre-strainer for the pump. It is the perfect solution for use as an emergency kit for single family houses in the event of flooding.

 

Applications

The Unilift CC is designed for the pumping of the following:

  • Water and rainwater in horticulture
  • Water from rivers and lakes
  • Rainwater, drainage water and water from flooding
  • Water for filling/emptying containers, ponds, tanks, etc.
  • Effluents from showers, washing machines and sinks below sewer level
  • Pool water

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

  • Grundfos-sq-CurvesDry-running protection
  • Permanent magnet motor with high efficiency
  • Wear resistance from floating impellers
  • Protection against upthrust

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).

Wilo-EMU 6" For potable water supply / general water supply from boreholes and rainwater storage

 

 

Design

Wilo Emu 6″ Submersible pump in sectional construction

Wilo-EMU_6-Vic

Description/design

Submersible-motor pump for vertical or horizontal installation.

 

Hydraulics

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.

 

Motor

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).

 

Cooling

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. A cooling jacket may be used to improve the inlet flow.

 

Pressure shroud

The pressure shroud is used for direct installation of the unit in the pipe system. Standard models are without mounted non-return valves. The maximum inlet pressure is 10 bar.

 

Application
