The Centrifugal Pump - KAMJaya

The Centrifugal Pump

In 1689 the physicist Denis Papin invented the centrifugal pump and today this kind of pump is the most used around the world. The centrifugal pump is built on a simple principle : liquid is led to the impeller hub and by means of the centrifugal force it is flung towards the periphery of the impellers.
The construction is fairly inexpensive, robust and simple and its high speed makes it possible to connect the pump directly to an asynchronous motor. The centrifugal pump provides a steady liquid flow, and it can easily be throttled without causing any damage to the pump.

If a pressure difference occurs in the system while the centrifugal pump is not running, liquid can still pass through it due to its open design.

The difference demands on the centrifugal pump’s performance, especially with regard to head, flow, and installation, together with the demands for economical operation, are only a few of the reasons why so many types of pump exist.

Planning guide

 

Inlet pressure

The maximum inlet pressure (see Technical data) must be taken into account when configuring the system. The maximum permissible inlet pressure is calculated from the maximum operating pressure of the system minus the maximum pump delivery head at Q = 0

Pressure reducer

Fluctuating inlet pressure is compensated by the speed control integrated into each single pump as long as the pressure fluctuation is not greater than the difference between the setpoint pressure value and the zero-delivery head of the single pump at minimum speed. If the pressure fluctuation is greater, a pressure reducing valve must be installed upstream of the system.

Volume flow

Up to 155 m3/h (43 l/s) system configuration in accordance with DIN 1988 (EN 806); with standby pump up to 185 mm3/h (51 l/s) during operation of the standby pump as an auxiliary peak-load unit

Residual-current-operated protection

switch

When installing residual-current-operated protection switches in conjunction with frequency converters, bear in mind that only universal-current-sensitive residual-current-operated protection switches in accordance with DIN/VDE 0664 are to be fitted.

Wilo-WMS low-water cut-out switchgear

The series Helix VE pump being used is already equipped with an integrated dry-running detection as safety equipment for the pump. Nevertheless, the installation of a low-water cut-out switchgear is required in cases where the pressure boosting systems are connected directly to a public mains power supply; that prevents the inlet pressure in the mains supply line from falling below 1.0 bar. Please order directly when ordering the pressure boosting system. The WMS will then be installed in the pressure boosting system, electrically wired and fully tested by Wilo during the final functional test.

Standards/directives

The overall system conforms with the requirements of

  • DIN 1988 Part 5
  • DIN 1988 Part 6* (**)

* The specifications in DIN 1988 (EN 806) and of the water-supply companies are to be observed. Regarding the electrical components, the system conforms with the requirements of

  • VDE 0100 Part 430/Part 540
  • VDE 0110 Part 1/Part 2
  • VDE 0660 Part 101/Part 107 and
  • DIN 40719/IEC 754

Always observe the specifications in DIN 1988 (EN 806) when using and operating the pressure boosting system.(**) That does not apply to fire extinguishing systems in accordance with DIN 14462. Please request these separately.

  • Shaft deflection meets the requirements of ISO 5199

 

Commissioning

 

  • If pumps with 2900 rpm are installed inside residential buildings, then corresponding noise reducing measures are to be implemented.
  • Pump curves and specific motor powers depend on the respective fluid being pumped. Pump curves and power vary considerably when fluids are conveyed that differ from water in thickness and/or viscosity. For this, please observe the table “Recommended limit values for dimensioning”.
    The recommended limit values for dimensioning are calculated as follows:
    Qoptimum (volume flow at which the pump reaches its best efficiency), to be read from the individual pump curve; factors Qmin and Qmax , to be taken from the table “Recommended limit values for dimensioning”.Qmin dimensioning = Qmin x Qoptimum
    Qmax dimensioning = Qmax x Qoptimum
    Example: Size NL 32-125
    Qmin = 0.3 x 8 = 2.4 m3/h
    Qmax = 1.2 x 8 = 9.6 m3/h
  • Load-sensitive pump output
    All Wilo standard pumps are equipped with IEC standard motors. The Wilo control devices are suitable for automatic load-sensitive speed control of pumps that are driven by any standard motors of conventional manufacture.
  • Main/standby mode

General notes – ErP (ecological design-) directive

 

  • The benchmark for most efficient water pumps is MEI ≥ 0.70
  • The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter.
  • The operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system.

Wilo-Jet WJ Curve

Drain TM/TMW/TMR 32 Series - Wilo Pumps

Design

Basement drainage water pump, water-cooled

Application in Water

  • For pumping water clear or slightly muddy water
    • From water tanks, sumps or pits
    • For water overflows and flooding
    • For draining water basement stairways and basement areas
TMR

The TMR is suited for lowering the water level to a remaining water level of 2 mm.

TMW

The service life of submersible pumps water, which are used in water pump sumps and through which washing machine water, soapy water from basins and showers, or other mixtures water flow, is considerably reduced by settling sediment. Such sediment can form deposits in the water pump sump, resulting in the accumulation of mud and odours.

Wilo-Drain water TMW 32 has a turbulator that prevents the build-up of sediment, expelling it together with the fluid in water. This reduces costs and the time needed for regular cleaning water of the sump. In addition, problems associated with mud removal and the observance of occupational safety hygiene regulations during cleaning water of the pump sump are minimized.

Description/design

Submersible pump water suitable for stationary, fully automatic operation. A pressure hose of appropriate length is connected for mobile use, while a pipe is connected to the pressure port for stationary applications. A residual current device for a trigger current of 30 mA that is to be provided onsite (regulation concerning outdoor installation) must be utilised in accordance with EN 60335-2,41.

The pumps of the TM series are suitable for drainage applications with a multi-channel impeller and a free ball passage of 10 mm according to EN 12050-2 (except TMR).

The water pump is continuously cooled by the fluid between the outside shroud of the water pump and the stainless steel motor housing. The serially installed thermal motor protection assures a permanent protection of the pump. The pump is equipped with a 3 or 10 m connecting cable with shockproof plug and a float switch (not TM 32/8-10M).

TMR

The Wilo-Drain TMR water pumps are built for special applications whereby it is essential to keep the amount of residual water low. The special strainer enables the fluid to be pumped out to a remaining level of 2 mm.

TMW

Due to its design, the Wilo-Drain TMW ensures constant turbulence in the suction area of the pump. This results in a clean pump sump.

No fluid-related odours are generated, due to the turbulence and the elimination of the settling sediment connected with it. The maintenance intervals are extended.

Deactivating the Twister (see installation and operating instructions) increases the pump curve by 1 m.

Motor

Jacket-cooled, stainless steel-encapsulated, dry electric motor with built-in thermal overload protection and automatic reactivation.

Cable

In accordance with DIN EN 60335-2-41, 10 m of electrical connection line should be used for outdoor operation (however note that regulations vary from country to country).

Sealing of water pumps/motor compartment

Mechanical seal on impeller side, one rotary shaft seal on motor side; there is an oil chamber between the seals.

 

Scope of delivery

Pump ready for connection with cable, plug and attached float switch (except for TM 32/8), supplied non-return valve (except for TM 32/7), installation and operating instructions.
