Shijiazhuang Ruite Pump Co., Ltd. is one of the most reliable manufacturers and suppliers of rubber liner slurry pump in China. Welcome to wholesale durable rubber liner slurry pump made in China here from our factory. All pumps are with high quality and competitive price.
Structure
Double casing structure
The outer layer is a pressure-bearing metal pump casing, and the inner layer is a replaceable rubber liner .
Shaft Seals
Common types include gland packing seal, expeller seal, and mechanical seal.
Structural form
The mainstream design is horizontal cantilever (RTH series), though vertical submersible (TSPR series) models are also available.
Characteristics of Rubber Materials
Main Materials
Natural wear-resistant rubber (high rubber content), synthetic rubber (butyl, neoprene), and polyurethane rubber.
High abrasion resistance
Excellent wear resistance.
Corrosion resistance
Resistant to weak acids, weak alkalis, and salt solutions; superior to high-chromium alloys.
Smooth surface
Low fluid resistance, high efficiency, and resistance to scaling.
Lightweight
40%–60% lighter than metal flow components, reducing motor load.
Temperature Limitations
Generally ≤70°C (specialty rubber required for high temperatures).
Not resistant to Sharp Particles
Sharp-edged, angular, or hard particles (such as quartz or iron ore) can easily cut or tear the rubber.
Lower Hardness
Service life is shorter than that of high-chromium alloys under conditions involving large particles or high concentrations.
Applicable working conditions (Key Selection Criteria)
Corrosive slurries: Acidic or alkaline mineral slurries with a pH of 2–12;
Wet desulfurization (FGD) limestone/gypsum slurry.
Fine particles, no sharp edges: Particles <10 mm in size with rounded or blunt edges (Gold mine, copper mine, coal slime, red mud, phosphate mine, tailings).
Typical Application Industries
Mining
Non-ferrous metal (copper, lead, zinc, nickel, molybdenum) ore beneficiation and tailings conveyance.
01
Power Generation
Wet flue gas desulfurization (FGD) systems (core pumps).
02
Coal
Coal slurry and heavy medium conveyance in coal preparation plants.
03
Chemical / Building Materials
Phosphate chemicals, titanium dioxide, ceramics, and cement raw material slurry conveyance.
04
Environmental Protection
Sludge, slurry, and acidic wastewater conveyance.
05
Common Models
Horizontal: RTH Series Slurry Pumps.
Vertical Submersible: TSPR Vertical Slurry Pumps.
Rubber liner slurry pumps are suitable for conveying fine-particle slurries.
Key selection criteria include particle shape, particle size, and temperature.
