Pump Impellers, Types and Impacts

Pump Impellers, Types and Impacts

The specification of the right centrifugal pump for an application involves various considerations. One of them is the right choice of impeller type. Each type of impeller offers different performance characteristics that make it suitable than the others for a particular application.

Main points to impeller selection:

1- Efficiency and NPSHr/a

2- Head & Flow

3- Material compatibility

4- Solid content handling

Main types of impeller:

1- Open impeller:

  • Has vanes that are open on both sides
  • To handle solid content
  • Require a higher NPSH

2- Semi-Open Impeller:

  • Has a back-wall shroud
  • Pumps with a small amount of soft solids

3- Closed impeller:

Pre Installation Procedure

Every pump is designed with lot of parameters to deliver its best performance. It is very mandatory to follow the pre Installation procedures as instructed by the brand to ensure its long life, trouble free operations, best performance and efficiency. Let us review the Pre-Installation procedure for a borehole Submersible Pumps.

Borehole Check & Preparation:

  • Check and ensure the inside diameter of the borehole whether it fits the pumpset selected.
  • If it is a newly drilled borehole it must be flushed well so that it is free from sand, silt and other foreign particles.
  • The pumpset should not be run dry and make sure the static water levels inside the borehole for proper submergence.

Preparing Pump and Motor:

  • Do not keep the bottom end of the motor in mud or dirt area. As this may block the diaphragm opening.
  • Check the freeness of the motor shaft and endplay.
  • Fill motor with clean, cold, drinking water through the water filling plug.
  • Check the motor for any water leakage, if noticed tighten all water filling plugs and drain plugs.
  • Measure the insulation resistance of the motor winding and resistance should not be lesser than 20 mega ohms.
  • A proper waterproof cable splicing must be done between motor lead and drop cable.
  • Run the motor for few seconds to ensure the direction of rotation. Do not run the motor in open condition for more time.
  • Couple motor and pump until it butts completely to the top surface of the motor.
  • Then tighten the nuts in a cross pattern uniformly.
  • Check axial movement of the pump shaft assembly by lifting it vertically up a minimum lift of 1 – 1.5mm will indicate that coupling is done properly.
  • Position the motor cable on pump and fix it with cable guard then fasten the suction strainer.
  • Never install the pumpset without suction strainer, as it may allow bigger solid particles and may go reason for pump failure.
  • Now set the pumpset inside the borehole above the yield point and well below the static water levels.
  • In case, if the yield point is not ascertain use the flow inducer sleeve along with the pumpset.
  • The pump must be installed at least 3 meters above the bottom level of the borehole.
  • Do not reduce the pipe size, use specified pipe size as per pump outlet size to get accurate discharge.
  • Install a good quality Non return valve to prevent water hammer and back spin.
  • After installation cover the borehole with right size borehole cap.

Field & Power Supply Checks:

  • The pumpset is designed to handle clean, cold, fresh water without abrasives.
  • Make sure that the voltage fluctuation lies within +/- 10% of the motor rated voltage.
  • Make sure the right cable size selections are done as per recommended by the manufacturer for power supply from control panel to motor.
  • It is mandatory to install the brand recommended control Box /Panels with complete protections against Voltage and Current faults.
  • All electrical connections are to be perfectly done without any loose connections in any terminals.
  • Proper earthing to be done for control panel and also earth cable to be connected with pumpset to avoid fatal electrical shock.

Pump starting & Final checks:

  • After all checks and installations are completed, can start the pump for testing and fine tuning.
  • Adjust the control panel settings as per factory instructed. Fine-tuning can be done to fit to the field conditions.
  • Ensure the rated voltage and Load currents are as per the rated. No Overloading of motors.
  • Water flow is as per the rated.
  • No water leaks on the pipe line.
  • Continue to run the pumpset for few minutes and ensure everything is perfect.

Brand’s Recommendations:

Tormac product goes through lot of inspections and quality checks before it gets delivered to the customers. If Installation procedures are followed perfectly, it ensures its best performance and returns to its owners.

Basics to know when buying a new Tormac pump

A pump is an electro-mechanical device used to transfer liquids from one place to another place using high hydraulic pressure. Read on to know about transferring liquids, and its types and how we are handling. Liquids can be water, oil, chemicals, acids, etc. Tormac products are designed to handle only water. The water may be drinking water, aggressive water, seawater, or wastewater. Depending upon water PH value, Hardness, Viscosity, Temperature, Sand content, Chlorine ion density the pumps vary with different construction and technical equipment.

Next, we need to understand the water source from where the pumping should happen, under the ground or Surface source. Tormac has a wide range of pumps that can transfer water horizontally, vertically, inclined and declined to a great distance, with different material of construction and sizes to match all your needs. But, it is important to identify the type that will work best for your needs.

To drive a pump, you need a motor that runs on electrical or mechanical energy. Tormac is manufacturing electrical motors of Water filled / Oil filled with a wide ranges.

Flow rate:

The flow rate (Q) of a pump is useful volume flow delivered through its outlet section. Volume, flows, upstream of the pump outlet section, and purpose is taken into account when calculating the pump flow rate. Each pump has a specified flow rate measured in Liters per second (lps) / Liters per minute (lpm) / Cubic meter per hour (m3/hr) / gallons per minute (GPM), as we have mentioned on the product page. If you have a high flow, you will need a large diameter pump. You also need to think about what you plan to do with the liquid, be it decanting or transferring. Tormac pumps have maximum flow rates up to 5000m3/hr. Depending upon its applications, the right flow rate and head are necessary parameters to start selecting a pump.

Maximum head (H) and pressure (bar):

The maximum head of a water pump refers to the longest distance in terms of vertical height or Horizontal height it will be able to pump water. If you are looking for the best water pump, you will see details such as nominal Head and maximum flow rates.

The piping has an impact on the "maximum head" pressure, and this is where the "rated head" is best to observe. The "nominal height" represents the ideal height for which you should consider using it - most pumps can't deliver above their nominal height. If you are measuring the height between your pump's location and your highest point of water access, you should have a good idea of the pump you will need. Tormac has pumps that can pump the water up to a maximum height of 820 meters.

Flow (Q) Vs Head (H):

Pump sizing involves matching the flow and pressure of a pump required for the process. The flow (Q) and head (H) both are reciprocal to each other. When the water is pumped to a great height, most of the energy will be consumed to lift the water, so the flow will reduce and vice versa. So, this is mandatory to understand this concept before you select any pump.

Inlet & Outlet Sizes:

Most pumps except borehole pumps have an inlet size between 1 and 6 inches but in some cases, it can be more. Centrifugal water pumps also operate in a similar way i.e. sucking in water from the inlet and discharging it through the outlet valve. In this case, the bigger size of an inlet valve, the more water can be pumped out and the faster it will do the job.

With Borehole pumps, as it submerges under the water there is no specific inlet valve as like in Centrifugal pumps. The interconnection between the motor and pump is the water inlet entry. Here we talk only about the outlet sizes in Inches or mm. One should know about the Outlet sizes for proper pipe selection and Valves selections. Tormac pumps got a sizes up to 6” under standard ranges. For customized can go even higher sizes. For personalized use, we can have even more sizes.

Starters and controls:

Tormac has specialized in bespoke control panels that meet the specific needs of domestic, industrial and specialty applications. It is mandatory to have the control panels specified by the brand for a perfect start, operation, stop and protection of the pump and the motor. If you install a good control panel, it can protect the products from failure. Tormac control panels are installed to ensure trouble-free operation, long product life, energy savings and high performance.
