What causes a water pump housing to crack?
Cracking Caused by Coolant When an engine overheats, you might think that the logical move is to help it to cool down by adding coolant. While this is a well-meaning move, it actually causes more harm than good. This sudden and rapid cooling cause a thermal shock and can crack the housing of the water pump.

Do I need to replace thermostat housing?
The thermostat housing and the thermostat itself are two different components and do not necessarily need to be replaced together or at the same time. The housing is just a piece that covers the thermostat that also has an opening for a radiator hose which is where the water enters and exits the motor.
What happens when thermostat housing breaks?
A faulty thermostat most likely causes it to remain in its closed position. This means when the engine is running hot and the coolant normally flows toward it, the closed thermostat will block the coolant from going into the engine. This will cause the coolant to overflow from the thermostat housing.
What is pump casing?
Pump casings serve to seal off the intside of the pump to atmosphere to prevent leakage and retain pressure. In the case of centrifugal pumps they surround the pump rotor which transmits energy to the fluid handled via the impeller(s) mounted on the rotating shaft.
What is water pump used for?
A water pump can drain water from a basement or shallow flooded areas, drain and fill a swimming pool or dam, or alternatively can also be utilised in the irrigation needed for agriculture. The main function of Water pumps is to get rid of excess water or transfer water between two points.

How does a water pump work?
The working principle of a water pump mainly depends upon the positive displacement principle as well as kinetic energy to push the water. These pumps use AC power otherwise DC power for energizing the motor of the water pump whereas others can be energized other kinds of drivers like gasoline engines otherwise diesel.
Why are water pumps needed?
Because of heavy rains, the flow of water can increase & water pumps let you supply the water rapidly to reduce downtime. These pumps are appropriate for applications like electric, hydraulic, gas-powered, and otherwise manual.
What is centrifugal pump?
Centrifugal pumps are designed with a rotating impeller which can be used for supplying the water into the pump and force the discharge flow. These pumps come in several types which includes trash, submersible, and standard models. By using these pumps, all types of liquids can be pumped with low-viscosity. And also these pumps work fine with thin fluids & gives high flow rates.
What is a positive displacement pump?
Positive displacement pumps supply a set amount of flow throughout the mechanical contraction and development of a stretchy diaphragm. These pumps are applicable in several industries that control high-viscosity fluids wherever responsive solids may be there. These are suggested for the applications wherever a combination of high pressure and low flow is required.
Why are rotary pumps so efficient?
Sometimes, these pumps are also called rotary pumps, and these are very competitive because of the fact that they remove air from the lines and therefore get rid of air leakage. These are also efficient while dealing with high-viscosity fluids. The main disadvantage of these pumps is that they need extremely little clearance among the revolving pump & the external edge of the unit. Consequently, the revolution must happen at extremely slow speeds. When the water pump is functioned at high speeds, then the fluid can ultimately decrease the efficiency of the pump.
