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

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
  • Ditch drainage water
  • Groundwater (lowering applications)
  • Effluents from viaducts, underpasses, etc.
  • Drainage water from garage sprinkler systems.

Grundfos-DPK are Submersible pumps for dewatering and draining applications

 

Overview

Grundfos-DPK-ModularGrundfos DWK and DPK are submersible pumps designed for dewatering and drainage applications. The cast-iron construction and the hydraulic design contribute durability and high efficiency.

The differences between the DWK and DPK pump ranges lie in the discharge arrangement and the installation type.

The DWK is designed with a top discharge pipe and suction strainer, and is thus more suitable for temporary installation, whereas the DPK has a side discharge and a ring-stand or auto coupling (as accessories), and is suitable for permanent installations.

 

 

 

 

General description

To ensure reliable and optimum operation, Grundfos
drainage pumps, type DPK, are designed with two
types of impeller:
• 0.75 – 15 kW models have semi-open impeller
• 19 and 22 kW models have closed impeller.
DPK pumps are used for removal of surface and
underground water in small and medium systems

 

Applications

DWK/DPK are excellent pumps for dewatering and draining applications. The combination of compact design with high-pressure capability makes the pumps suitable for use in pits, whether for temporary or fixed installation. The installation design options provide the flexibility needed to cover many needs. Applications include:

  • Construction sites
  • Excavations
  • Tunnels
  • Fish ponds
  • Drainage pits.

 

Operating conditions

The DPK pump range is suitable for two operating
modes:
• continuous, submerged operation, S1, with min.
liquid level above the pump
• intermittent operation, S3, with the pump partly
submerged.
See fig. 1

pH value
DPK pumps in permanent installations can cope with
pH values ranging from 4 to 10.

Liquid temperature
0 °C to +40 °C.

Grundfos-DPK-Curves
