A ceramic piston pump comprises of a piston that reciprocates within a cylinder with a seal. The piston is forced to move up and down the cylinder by a rotor to which it is connected. When the piston moves upward and outward, water is drawn into the cylinder through the intake valve. And water is pushed out through the outtake valve as the piston is pushed back via the cylinder.

Unipretec uses 99% alumina ceramics to produce ceramic pistons. By using high-precision internal and external grinding machine, the ceramic piston is polished into a mirror effect surface with roughness Ra0.2-0.4um. A smooth surface makes the piston self-lubricating and reciprocating friction reduced.

The outer diameter and inner diameter of the ceramic pistons are machined into a high precision standard. It ensures a good sealing of assembly and avoid water leaking into the oil tank, which causes the oil to turn into a white turbid liquid in the crankcase.

In the market, there’re also ceramic coated pistons. In comparison, ceramic pistons are brittle, but coated pistons are not easy to get broken. And the ceramic coating layer protects pistons from abrasion, reducing friction and improving heat shield. But the coating layer is easy to peer off, and without protection of coating layer, the pistons will get wear out by continuous friction, and water leaking into oil crankcase will occur after a period of use.

Unipretec produces wholesale ceramic pistons for pressure washer pump, and the price is favourable for wholesale quantity.

Features

Extremely high hardness of the ceramic material means that the ceramic piston wears very little when it comes into touch with the pump body. A longer service life for the piston is therefore made possible.

High temperature resistance makes the ceramic piston perfect for use in high-temperature activities. It will not suffer any kind of distortion or damage from the temperature increase.

Strong resistance to most chemical corrosion allows the ceramic material to continue functioning even in the presence of corrosive substances.

Good sealing: Liquid leaks are stopped, the cleaning action is guaranteed, and a good sealing effect is provided by the close fit between the ceramic piston and the pump body.

High hardness and strength: Suitable for the working environment of high-pressure cleaning pumps, the ceramic piston can withstand high pressure and impact loads. High-pressure cleaning pumps may also employ the ceramic piston.

Because ceramic material has a low thermal expansion coefficient, it helps to maintain the piston's dimensional stability as temperature varies. The ceramic material's low thermal expansion coefficient explains this.

Self-lubricating characteristics of the ceramic piston reduce friction and wear during operation and performance maintenance costs.

Electrical insulation: A nice material for making electrical insulation, ceramic is especially useful in a number of seldom utilized applications.

Biocompatibility: In certain uses that are not thought to be broadly applicable, ceramic piston biocompatibility is also an important factor.

Environmentally friendly: Ceramic material meets modern industrial requirements for environmental preservation and is free of harmful chemicals.

Application Areas

Ceramic pistons are highly sought after in the following industries for use in high-pressure cleaning pumps:

Known also as general cleaning, industrial cleaning is used to clean industrial equipment, pipes, and containers.
Used in high-pressure car washing of the interior and external surfaces.
Cleaning ships include removing marine life off the hulls and cabins of the ships.
Cleaning outer walls, floors, and other surfaces of buildings is referred to as "building cleaning".
used to clean food processing equipment so as to ensure food safety throughout processing.

Pump for cleaning at high pressure With its remarkable performance capacity and wide variety of possible uses, ceramic pistons are becoming a more and more necessary part of high-pressure cleaning equipment. Ceramic pistons will perform noticeably better and find a larger variety of applications as the disciplines of materials science and manufacturing technology develop. Because ceramic pistons withstand corrosion, wear, and high temperatures, they are a necessary part of high-pressure cleaning pumps.
