How does a Godwin pump work?
Compressed air (1) travels through the Godwin venturi (2) creating a vacuum by evacuating air from the pump body and suction hose (3), while the non-return valve ball (4) seals out air from the discharge, allowing fluid to enter the pump body (5) and begin pumping.

What are dewatering pumps?
A dewatering pump is a centrifugal pump that is used wherever you need to remove water. You can use the pump at construction sites, in tunnels and mines and also in buildings where you need to remove unwanted water.
What happens if you don’t prime water pump?
If you don’t prime your pump, you risk mechanical seal failure, and further damage to other necessary pump components. Without proper priming, your water pump’s motor will still run, but you’ll notice low water pressure, or no fluid delivery at all.
What causes a water pump not to prime?
Debris blocking the suction strainer or foot valve is the most common cause. A blockage in the intake line can cause the water in the pump casing to overheat and literally boil out of the casing causing the pump to lose prime.
What causes a pump to lose its prime?
Causes of Pump Losing Prime
If there’s no water in the line, air gaps cause suction to stop. Your well pump begins cycling air instead of water. Well pumps can lose their prime for several reasons. If your well water level is too low, you may have pulled too much water from the system.
Which pump does not need priming?
Normally, Centrifugal pumps need priming and Positive Displacement Pumps (Rotary Pumps, Reciprocating Pumps) does not require priming.
What can I use to pump out water?
Utility pumps are used for short-term purposes or emergencies to transfer liquids from one place to another. If you’re just moving water, go with a utility pump. However, if the water contains debris or solids, go with a trash pump or sewage pump, instead.
What are the methods of dewatering?
Main dewatering techniques
- Wellpoints. In Wellpoint, wells are drilled around the excavation area with submersible pumps installed in the well shaft.
- Deepwells. In Deepwell, one or several individual wells are drilled, and submersible pumps are placed in each shaft.
- Bypass dewatering.
- Flood control.
- Tunneling dewatering.

What happens if a pump is not primed?
What happens when a pump loses prime?
No water pressure due to lost pump prime: IF you have no water pressure, absolutely no water in the building water supply piping, and no water in the water pump itself, THEN we’ve lost prime and the one line or two line jet pump may be unable to bring water back from the well.
How do I stop my water pump from losing prime?
Steps To take If Your Pump Is Losing Its Prime
Ensure that the pipe connections threaded into the housing are tight and that the intake line is not cracked or has any loose or poorly glued fittings. Valves-Most pumps are equipped with foot valves to keep water in the intake line and casing when the pump is not running.

- Replace gauge and bushing or tank, TIGHTEN.
- Turn power on.
- Open faucet or hose bib at pump to bleed air from system.
What happens if pump is not primed?
Which pumps are self priming?
Centrifugal pumps with an internal suction stage such as water jet pumps or side channel pumps are also classified as self-priming pumps.

Which is the most effective method of dewatering?
Sump Pumps
Sump pumping is the most common method for dewatering, since it basically works by gravity. This method is also the most economical. Groundwater is allowed to seep into the excavation area, where it is collected in sumps to be pumped out.
What are 2 methods of dewatering?
We have singled out four commonly used methods: sump pumping, wellpoints, deep wells, and eductor wells. These techniques can be employed singularly or in combination depending on the nature of the soil and groundwater conditions.
Why does my water pump keep kicking on and off?
A blockage in the water supply piping.
For example, a clogged or nearly clogged water filter can cause the pump control to cycle on and off rapidly. This is because the blockage causes water pressure (between the pump and the filter) to rise very rapidly when the pump turns on.
