3/2C THR Rubber Pump Description
When handling highly abrasive or corrosive slurries, standard metal pumps often fail prematurely. The Tobee 3/2C THR Rubber Centrifugal Pump solves this problem with its elastomer-lined design. As a Rubber Impeller Slurry Pump for Corrosive Applications, this unit excels where acids, fines, and aggressive chemicals destroy conventional equipment. This 3x2C Slurry Pump for Abrasive Handling delivers reliable uptime in mining and chemical plants. What makes it truly unique? It is a Centrifugal Slurry Pump with Rubber Lined Impeller that absorbs impact rather than wearing down. This Compact Slurry Pump with 3 Inch Inlet fits into tight retrofits while moving up to 75.6 m³/h. Let us explore why this Corrosion Resistant Slurry Pump with Rubber Parts outperforms metal alternatives.
The Industrial Slurry Pump for Wear Resistant Applications from Tobee® addresses three common pain points: rapid part failure, unplanned downtime, and high replacement costs. Traditional metal pumps experience galvanic corrosion and erosion from fine particles. Rubber, however, offers a "rebound effect" – particles bounce off the soft liner, dissipating kinetic energy without cutting into the surface. For slurries containing sand, tailings, or chemical precipitates, this translates to 2–4 times longer wear life compared to hard metal alloys.
Key operational benefits include:
Lower total cost of ownership – Replaceable bolt-in liners (not glued) reduce maintenance hours
Short, rigid shaft design – Minimizes deflection, extending seal and bearing life
Interchangeable parts – Fully compatible with original industry standard 3/2C-AHR models
7 Design Features of the Tobee® 3/2C THR Rubber Pump
Engineered for harsh continuous duty, this Centrifugal Slurry Pump with Rubber Lined Impeller incorporates these seven design elements:
Engineered Rubber Impeller – The Rubber Impeller Slurry Pump for Corrosive Applications uses a molded, vulcanized rubber impeller with swept-back vanes that reduce recirculation and prevent solids from packing.
Bolt-In Rubber Liners – Unlike glued liners that require curing time, these replaceable elastomer liners (natural rubber, EPDM, or nitrile) bolt directly into the casing for rapid field replacement.
Cantilevered Horizontal Design – Single-stage, overhung arrangement keeps the bearing assembly isolated from the wet end, preventing contamination.
Three-Inch Suction Inlet – The Compact Slurry Pump with 3 Inch Inlet maintains NPSH requirements while handling slurries with up to 6mm particle sizes.
Two-Inch Discharge Outlet – Matches standard piping schedules for easy integration into existing slurry circuits.
Multiple Sealing Options – Choose between gland packing, expeller (centrifugal seal), or mechanical seals depending on application pressure and solids concentration.
Heavy-Duty Bearing Assembly – Pre-lubricated, grease-lubricated tapered roller bearings rated for 30 kW maximum power input.

Mining & Mineral Processing – Cyclone Feed and Mill Discharge
In mineral processing circuits, the 3x2C Slurry Pump for Abrasive Handling moves cyclone feed slurries containing 30–50% solids by weight. Rubber liners resist erosion from fine silica, copper ore, and gold tailings where metal pumps would show groove wear within weeks. Operators report 8,000+ hours on rubber parts before first liner rotation – significantly longer than Ni-hard or high-chrome alloys in the same service.
Chemical Industry – Corrosive Acid Slurries
The Corrosion Resistant Slurry Pump with Rubber Parts handles aggressive mixtures including sulfuric acid with solids, titanium dioxide slurries, and brine solutions. Natural rubber liners resist most acids below 60°C, while EPDM options cover alkalis and oxidizing chemicals. Unlike metal pumps that suffer pitting and stress corrosion cracking, the rubber lining remains chemically inert and maintains hydraulic efficiency.
Frequently Asked Questions
Q1: Can the Tobee® 3/2C AHR Rubber Centrifugal Pump handle sharp, angular particles like crushed glass or slag?
No. Rubber-lined pumps are optimal for fine to medium particles without sharp edges (e.g., sand, tailings, milled ore). For sharp, angular materials, a metal-lined AH pump is recommended because jagged particles can cut into rubber surfaces. Always conduct a slurry abrasivity test before selecting materials.
Q2: How do I know when to replace the rubber impeller or liners?
Monitor two indicators: (1) A 15–20% drop in flow or head at constant speed suggests wear gap enlargement. (2) Visual inspection during scheduled maintenance – replace when liner thickness reduces by 40% or when the impeller vanes show undercutting. Most users schedule liner replacement every 6–12 months depending on slurry density.
Q3: Is the Tobee® rubber pump compatible with original standard 3/2C parts?
Yes. All dimensions, bolt patterns, and mounting interfaces follow the industry standard established decades ago. You can replace worn rubber parts with Tobee® components without modifying existing piping or baseplates. This interchangeability minimizes inventory complexity.
