Tricel Pumps Frequently asked questions
What are different types of pumps?
Basically, there are two types of pumps: A Centrifugal Pump B: Positive Displacement pump!
Positive Displacement = rotary lobe pump, progressive cavity pump, rotary gear pump, piston pump, diaphragm pump, screw pump, gear pump, Hydraulic pump, vane pump
Centrifugal Pumps = end-suction pumps, in-line pumps, double suction pumps, vertical multistage pumps, horizontal multistage pumps, submersible pumps, self-priming pumps, axial-flow pumps, regenerative pumps.
What is the basic difference between single-stage and multi-stage centrifugal pump?
The Single-stage pump has one impeller and the multi-stage pump has two or more impellers in series!
What is a wet-running pump?
In this pump design, all rotating parts (shaft, rotor, impeller) are located within the can in the pumped medium. Cooling and lubrication are provided by the pumped medium.
How Cavitation Can Be Eliminated In A Pump?
Cavitation means bubbles are forming in the liquid.
To avoid cavitation, we have to increase the pump size to one or two Inch;
To increase the pressure of the Suction Head, or decrease the pump speed.
Why Cavitation will occur in centrifugal pumps and not In displacement pumps?
The formation of cavities (or bubbles) is induced by flow separation, or non-uniform flow velocities, inside a pump casing.
In centrifugal pumps, the eye of the pump impeller is smaller than the flow area of the pipe. This decrease in flow area of the pump results in an increase in flow rate.
So pressure drop happened between the pump suction and the vanes of the impeller.
Here air bubbles or cavities are formed because of liquid vapour due to an increase in temperature in the impeller. These air bubbles are transmitted to the pump which forms cavitation.
How do I choose a water pump for domestic use?
The higher it is, the quicker it pumps. A range of 100-200 LPM is usually sufficient for a household.
Head Range – Head here refers to the discharge head – the vertical distance that you will be pumping the water.
The head range should fall within this distance for the water pump to pump water effectively.
What is the difference between a wastewater pump and a drainage pump?
A drainage pump is primarily intended for pumping surface water and seepage to different locations, and for the pumping of groundwater.
Wastewater pumps on the other hand are primarily used to dispose of wastewater. This includes e.g. pumping wastewater out of collector pits and pumping station applications.
