The slurry pump frame plate liner( back liner) is a core wearable wet-end component of slurry pumps. It is available in high chrome alloy and wear-resistant rubber, compatible with ZJ, AH, ZGB and other full-series slurry pumps. It is widely used in mineral processing, coal washing, sand transportation, power plant desulfurization, tailings discharge and other working conditions. It can isolate slurry impact and abrasion on the pump shaft, casing and impeller, reduce equipment failures and extend the overall service life of the pump. 

Product Advantages

1.Excellent wear and erosion resistance High chrome alloy is heat-treated at high temperature with high hardness to resist continuous cutting and scouring of sand and slag. The rubber liner features high elasticity to buffer particle impact and avoid cracking and perforation. Isolate slurry to protect core pump components It effectively prevents slurry from corroding shaft sleeves, bearing positions and pump casing, avoiding damage to main pump parts. 

2.Maintenance can be completed by only replacing the liner, greatly cutting maintenance costs. Precise forming with superior hydraulic performance Integral casting or molding ensures accurate dimensions to fit the pump chamber. It optimizes internal flow passages, reduces vortex resistance, improves pump conveying efficiency and saves power consumption. 

3.Good corrosion resistance for harsh working environments High chrome alloy withstands weak acid and alkali slurry; wear-resistant rubber resists sewage and desulfurization slurry corrosion, preventing scaling and flow blockage for various corrosive slurry transportation. 

4.Complete specifications & easy installation It matches most mainstream slurry pump models with interchangeable OEM standard sizes. The simple structure enables quick disassembly and assembly to minimize equipment downtime.
