Increase the efficiency and performance of your water pump with polymer coating

In a typical water pump system, a lot of power is spent on pumping. With energy prices going up, pump owners are looking for technologies to enhance operational efficiency. A fantastic method to improve the efficiency of water pumps is to have a professional line them up with polymeric coating systems, to guarantee increased water flow at the right pressure and reduced energy consumption. Read on for more insight.

What causes energy loss in water pumps?

A significant portion of the energy used in pumping water is actually used in combatting frictional drag along the water lines. In fact, water flow in a water pump is exposed to resistance triggered by volute and impeller surface abrasion and viscosity. In water dynamics, water particles on the pump surfaces remain stationary. Distinct water particles in the flow act as detached entities producing waterspouts and cross-currents which lead to energy losses as well as those emanating from skin friction. Surface roughness, thus, often caused by skin friction is a key factor in explaining energy losses in a water pump. Even polished water pump surfaces are discovered to be somewhat rough when assessed under high magnification. What's more, surface roughening may be as a result of cavitation effects or erosion-corrosion, therefore resulting in pump inefficiency.

How polymeric coatings function

Basically, polymer coatings are distinctly designed as smooth surface veneers with minimal surface energy and friction resistant fillers. In fact, they create a very smooth surface which minimizes internal pump turbulence, hence enhancing hydraulic efficiency. The coating's ultra-smooth nature causes water to essentially roll off the surface. Further, wear caused by friction is highly reduced by its condensed combination of lubricating agents and friction resistant fillers. When applied to a water pump equipment, polymer coatings prove to enhance overall efficiency through reduction of power consumption and increasing water flow pressure or rates.

Application

In a normal application, two coatings of distinct colours are applied by spray or brush at a particular thickness. The self-levelling characteristics of the coatings guarantee a smooth surface finish. Both the coating thickness and the finish are key factors behind pump efficiency without affecting the water flow features of the water pump. In old water pumps, any badly worn or rutted sections may be restored back to the original shapes through the use of a paste grade repair polymer compound prior to coating.

In conclusion, water pump owners should consider having their pumps lined up with polymer coatings by a professional for increased overall pump efficiency.
