Product Category

Compared with the metal plunger, the ceramic plunger has the remarkable characteristics of low surface roughness, low friction resistance, high temperature resistance, corrosion resistance, etc. Its designed use time is 3 years. The series of alumina zirconia ceramic plungers produced by precision processing are widely used in petroleum, chemical, food, textile, medical and other industries.

1. Zirconia ceramic plunger

The ceramic plunger has extremely high wear resistance, corrosion resistance and impact resistance. The matching accuracy between the shaft core and the outer casing of the ceramic plunger can reach 0.001mm, and the smoothness can achieve a mirror effect, thereby reducing the friction coefficient and greatly improving the The use time of the plunger improves the boot efficiency. The ceramic plunger is formed by isostatic pressing to ensure the consistency of density, so that it will not crack due to density doubts during work. The surface is finely polished with diamonds to minimize the surface roughness to increase lubricity and durability. . According to the shortcomings of poor corrosion resistance and short service life of the metal plunger used in the plunger pump used in the current petroleum, chemical, food machinery and other industries, as well as the current situation that the existing ceramic plunger is unreliable and easy to fall off. A high-tech commodity.

2. Zirconia ceramic plunger rod

Its characteristic is that the contact surface with the medium and the working surface are all zirconia ceramics, the plunger rod and the metal handle are mechanically combined, and the adhesive is filled between the ceramic piece and the metal handle. Avoid loose threads. Compared with the existing ceramic plunger, it has the characteristics of anti-drop, reliable joint and high strength.

Application

The plunger is part of the pump and in use only comes into contact with the seal/packing and the pumped medium. However, if high pressures, highly abrasive or corrosive media or very high line speeds are encountered, the plunger is made of ceramic material. And the ceramic plunger made of different ceramic materials, their application range is not the same. Ceramic plungers are suitable for most brine, chemical and metering applications. IEQ (Indoor Environmental Quality) specially formulated ceramic grades achieve a standard 8 RMS surface finish, significantly extending filler life.

IEQ (Indoor Environmental Quality) ceramic plungers are available in hollow ceramic designs and solid ceramic designs. The IEQ (Indoor Environmental Quality) adapters are made of durable stainless steel that successfully resists corrosion. The ceramic body is bonded to the stainless steel adapter using a proprietary process for extremely reliable performance in the field.

When corrosion and wear resistance is required and extended packing life is required, ceramic plunger performance is unmatched. However, ceramic plungers are not optimal for all applications. For example, they are not recommended for pumping hazardous materials.

Applications of Plunger alumina ceramic parts: hydraulic cleaning equipment; power units in mining; metering pumps (distribution pumps); high pressure pumps for water jet cutting.
