Rubber Sand Pump Description
Tobee® Rubber Sand Pump with 2 Inch Inlet and Slurry Pump with 1.5 Inch Outlet forms the perfect 2x1.5 pumping system. As a Tobee Rubber Impeller Pump for Sand Transfer, this Compact Sand Pump with Rubber Lined Casing offers exceptional durability. The Industrial Sand Slurry Pump for Dredging Applications handles tough fine sand and slurry with ease, making it a reliable choice.
Looking for a pump that can handle abrasive fine sand day after day without breaking down? Many operations struggle with rapid wear and frequent maintenance when pumping sharp, corrosive slurries. The Tobee® 2/1.5B THR Rubber Centrifugal Sand Pump is specifically engineered to solve these problems.
This heavy-duty unit is a horizontal cantilever pump that relies on high-quality rubber lining to protect its internal components. Unlike traditional hard metal pumps that rely on brute strength, this rubber-lined design absorbs the kinetic energy of solid particles. The result is a significantly extended service life, even in the harshest environments.
In short, this is a centrifugal pump optimized for fine particle slurries without sharp edges. Its rubber construction provides superior resistance to both abrasion and chemical corrosion.
Design Features of the Tobee® THR Rubber Sand Pump
The performance of this Compact Sand Pump with Rubber Lined Casing is rooted in four core design elements:
Heavy-Duty Ductile Iron Casing with Full Rubber Lining
The external casing is cast from robust ductile iron, providing the strength to withstand high operating pressures. The internal surfaces are fully lined with premium elastomers, including natural rubber and synthetic compounds. This dual-layer construction delivers both structural integrity and superior wear protection.
Large Diameter, Slow-Turning Rubber Impeller
As a Tobee Rubber Impeller Pump for Sand Transfer, the unit features a specially designed impeller made from high-grade rubber. The large diameter allows for slow rotation speeds, which drastically reduces internal turbulence and particle impact velocity. A rubber impeller absorbs shocks from small abrasive materials, extending its life far beyond that of a metal impeller.
Cartridge-Style Bearing Assembly
The bearing assembly features a large-diameter shaft with short overhang, reducing deflection and vibration. A grease-lubricated cartridge design allows maintenance to be performed in a clean workshop environment without completely dismantling the pump, leading to less downtime and longer bearing life.
Versatile Shaft Seal Options
Depending on your specific need, the pump can be fitted with a packing seal, expeller seal, or a mechanical seal. This modular design allows the Industrial Sand Slurry Pump for Dredging Applications to adapt to various operating conditions, whether handling fine tailings or coarse sand.

️ Mining & Mineral Processing — Tailings Transpor
In mining operations, the safe and efficient handling of tailings is a constant challenge. These fine, abrasive slurry mixtures quickly erode standard metal pumps, leading to costly replacements.
The Tobee® Rubber Sand Pump with 2 Inch Inlet is engineered for this very application. The rubber lining absorbs impacts from fine particles without surface cutting or scratching. The Slurry Pump with 1.5 Inch Outlet connects seamlessly into the processing line, maintaining a consistent flow for transfer to tailings dams or thickening circuits. By using a rubber impeller, the pump maintains high efficiency even as it handles solids concentrations commonly found in mill discharge and cyclone feed operations.
Chemical & Industrial — Corrosive Slurry Transfer
Processing corrosive waste streams and industrial slurries requires more than just abrasion resistance; it demands chemical resilience.
The Tobee Rubber Impeller Pump for Sand Transfer utilizes specially formulated elastomers (such as neoprene or nitrile) that resist aggressive chemicals while handling fine solids. Whether the task is moving acidic tailings in a chemical plant or handling gypsum slurry in a Flue Gas Desulphurization (FGD) system, the rubber casing prevents chemical attack that would destroy standard metal pumps. This makes the pump an ideal choice for continuous, long-term service in aggressive industrial environments.
Frequently Asked Questions (FAQ)
Q1: What is the main difference between the rubber-lined THR and metal-lined pumps?
A: The key difference is the material of the wetted parts. The Tobee® Rubber Sand Pump with 2 Inch Inlet uses natural or synthetic rubber liners and impellers, while the metal-lined version uses high chrome alloy. Rubber is better suited for fine, non-sharp, abrasive slurries, especially in low-pH conditions, because it absorbs particle impact rather than letting it erode the surface.
Q2: Can this Slurry Pump with 1.5 Inch Outlet handle large, sharp solids?
A: It is not recommended. Rubber-lined pumps, including this model, are designed for fine particle slurries without sharp edges. If your slurry contains large or jagged rocks, a metal-lined pump (like the original metal version) would be a better choice.
Q3: What types of seals are available for this pump?
A: The Industrial Sand Slurry Pump for Dredging Applications offers three sealing configurations: gland packing seal (with flush water), expeller seal (centrifugal dynamic seal), and mechanical seal for zero leakage. Your choice depends on your site’s flushing water availability and specific slurry characteristics.
Q4: Are the rubber components interchangeable with other brands?
A: Yes. Tobee® designs its rubber liners and impellers to be 100% interchangeable with other industry standard models. This ensures you can easily source replacement parts without supply chain delays.
Q5: What is the typical flow range and head for the 2/1.5B THR model?
A: This model typically delivers a capacity ranging from approximately 25.2 to 54 m³/h, with a head capability between 5.5 and 41 meters, depending on the operating speed and impeller size.
Final Recommendation
Choosing the right pump for abrasive sand is about more than just specifications—it's about long-term reliability and lower costs. The Tobee® Rubber Sand Pump with 2 Inch Inlet and Slurry Pump with 1.5 Inch Outlet ensures efficient transfer. Featuring a rubber impeller, it excels as a Compact Sand Pump with Rubber Lined Casing.
