1. General description
Minimum efficiency index
Minimum efficiency index (MEI) means the dimensionless scale unit for hydraulic pump ef ficiency at best efficiency point (BEP), part load (PL, 75 % BEP) and overload (OL,110 % BEP). The Commission Regulation (EU) sets efficiency requirements to MEI ≥ 0.40 as from 1 January 2015. An indicative benchmark for best-performing water pump available on the market as from 1 January 2013 is determined in the Regulation.
• 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.
• Information on benchmark efficiency is available at http://europump.eu/efficiencycharts.
SP pumps are primarily used to pump raw water from the underground. The pumps are installed in boreholes or wells, submerged below the water level. For industrial purposes, you can place the pump in for example a tank. The SP A and SP pumps are suitable for the following applications:
• raw-water supply
• irrigation
• groundwater lowering
• pressure boosting
• fountain applications
• mining applications.
• off-shore applications.
2.Submersible pumps
Features and benefits
A wide pump range
Grundfos offers energy-efficient submersible pumps ranging from 1 to 330 m3/h. The pump range consists of many pump sizes, and each pump size is available with an optional number of stages to match any duty point.
High pump efficiency
Often pump efficiency is a neglected factor compared to the price. However, the observant user will notice that price variations are without importance to water supply economics compared to the importance of pump and motor efficiencies.
Example
When pumping 200 m3/h at a head of 100 m for a period of 10 years, a normal pump consumes about 688,000 kWh. If the pump/motor efficiency is enhanced by 5%, you can save about RM 34,000 in energy cost, if the price is RM 0.10/kWh.
Material and pumped liquids
To ensure the right wear resistance and reduce risk of corrosion, the pump ranges are available with different steel variants.
• SP: EN 1.4301
• SP N: EN 1.4401
• SP R: EN 1.4539
See specified material variants in section Pump range. For further protection to corrosive environments, a complete range of zinc anodes for cathodic protection is available. See section Zinc anodes.
Rubber components
For pumping liquid with risk of chemical residue or liquids > 60 °C, all pumps can be supplied with rubber components made of FKM elastomer.
Low installation costs
Stainless steel means low weight facilitating the handling of pumps and resulting in low equipment costs and reduced installation and service time.
3.Operating conditions
To ensure long and trouble-free pump life, it is important that the following is observed.
Inlet pressure
The minimum inlet pressure is indicated by the NPSHcurves in the single-stage curve charts.
The minimum safety margin of the NPSH-curves must always be 0.5 m head.
Minimum flow rate
To ensure sufficient cooling of the motor, the pump must not run continuously at a flow rate below 0.1 × nominal flow rate.
Operation of the pump against a closed valve must be limited to a maximum of 30 seconds due to the risk of local heating of the pumped liquid and the consequent
damage to the pump and motor.
Maximum flow rate
The pump must not run continuously at a flow rate above 1.3 × nominal flow rate due to the risk of upthrust and cavitation.
Pumped liquids
SP A and SP pumps are capable of pumping clean, thin, non-aggressive liquids, not containing solid particles or fibres larger than sand grains.
Special liquids
A larger content of sand will reduce pump life.
The special SP A-N and SP-N versions made of stainless steel to EN 1.4401 and SP A-R and SP-R versions made of stainless steel to EN 1.4539 are available for
applications involving aggressive liquids.
Pumping of liquids with a higher density than that of water requires a motor with a correspondingly higher output.
Pumping of liquids with a higher viscosity than that of water may result in
• increased pressure loss
• reduced hydraulic performance
• increased pump power input.
In case of doubt, contact General Intelligence Sdn Bhd or Grundfos.
Liquid temperature
For protection of pump and motor rubber parts, the liquid temperature must not exceed 60 °C.
Alternatively, you can fit the pump with bearings made of FKM material, resistant to liquid temperatures of up to 90 °C.
