Pistons With Replacement Rubbers

  Our piston hubs are manufactured from AISI 5140 heat-treated forged alloy steel machined on modern CNC lathes to exact dimensions.They meet all API tolerances and different temperature applications.They are available in size 3" to 8" in series A,K,B and L with types of duplex and triplex.

  Our pistons are made with tough and durable rubber for all pressure , available in single-acting and double –acting in variety sizes for most pumps , especially in.

     *Long-life Bonded Piston with Ruber and Fabric.

     *Long-life Bonded Piston with Urethane(PU).    

*Long-life Bonded Piston with NBR.

     All the above pistons and piston rubbers , which are ideally suitable for either oil-base or water-base muds , can be ensured universal interchanged ability , Max service life and Min liner wear. When you have a chance to examine them , you will not be surprised to agree that Max Running at Min Cost . ZhiFeng also offers the relevant piston rubbers made of Rubber with Fabric , NBR , and Urethane .
