Ceramic Piston Pump / Ceramic Dosing Pump for Drink Beverage Liquid Machinery
Key words : Ceramic Piston Pump / Ceramic Dosing pump
Ceramic Pistons and sleeves in ceramic materials are a specialty of Mingrui Since 2008 , Mingrui has been precision machining and polishing of ID's and OD's allowing mingrui to meet the toughest customer requirements for minimum clearance, seal-less metering pumps. Some designs in alumina or sapphire achieve clearance of less than .0005" on two-inch long travel. Other customer designs in polished quartz or polished sapphire allow observation of combustion conditions for IC engine research.
Mingrui is a precision machining company that fabricates parts from all technical ceramics, sapphire, glass and quartz. They machine these materials to very precise tolerances for dimension, also flatness, wedge, roundness, and cylindricity, etc as required by their customers. They welcome developmental parts as well as production requirements. Engineers are available to discuss practicality of alternatives for your application including material and cost drivers. See their website for more information including available material properties with an interactive Designer's Guide.
Advantages of ceramic piston pump :
- High strength
- High fracture toughness
- High hardness
- Wear resistance
- Good frictional behaviour
- Non-magnetic
- Electrical insulation
- Low thermal conductivity
- Corrosion resistance in acids and alkalis
- Modulus of elasticity similar to steel
- Coefficient of thermal expansion similar to iron
Industrial ceramic can be processed in shaft , plunger, sealing structure, auto mobile Industrial parts, oil drilling equipment pieces, Insulation parts in electrical equipment , ceramic knife, ceramic flange parts,etc, with high density, bending strength and breaking tenacity

Q: How can i get a quotation ?
A: Please send your drawing or the details of your demand to us, then we will quote to you.
A: Generally it will take about 15-30 days because the production process is a long time cycle, but if we have stock of the products you need, then we can ship out once we get the payment.
Q:What about the package?
A:We pack with plastic bubble paper, carton box, then safe wooden box outside, we can control the breakage less than 1%
