SPR4041 Rubber Back Liner for 40PV-SPR Rubber Lined Vertical Sump Slurry Pump
SPR4041 rubber back liner is essential wet end wear spare part for 40PV-SPR vertical slurry pump. Molded from R55 natural rubber with good elasticity, tear resistance and mild anti-corrosion performance. It protects pump frame plate and reduces backflow abrasion, perfectly matched with SPR4206 impeller and SPR4092 casing.
SPR4041: Standard part number of back liner for SPR series vertical sump slurry pump.Rubber: Natural rubber material, offering excellent corrosion resistance for corrosive slurry with fine particles.40PV-SPR: Matching pump model, 40PV-SPR vertical cantilever sump slurry pump.
The SPR4041 rubber back liner adopts integrated molding technology with optimized hydraulic profile. The elastic rubber surface cushions impact from fine solid particles and reduces wear. It performs excellently against mild acid, alkaline and corrosive slurries. Precise molding guarantees stable dimensional accuracy and full interchangeability with OEM spare parts. Cooperates well with rubber impeller to maintain reasonable clearance and stabilize pump hydraulic efficiency.
Customized for the 40PV-SPR vertical sump slurry pump.Compatible with SPR4206 rubber impeller and SPR4092 rubber casing of the 40PV-SPR pump unit. Fits vertical cantilever structure without submerged bearings. After replacement, the pump retains original flow rate and head performance.
Suitable for transporting corrosive slurries mixed with fine solid particles. Widely used in mineral processing, chemical industry, wastewater treatment and sand separation under low and medium abrasion conditions. Not recommended for slurries containing large, sharp hard particles.
