Selecting a rubber lined slurry pump starts with the slurry and the duty point—not with the pump name or pipe size. I recommend confirming required flow, total dynamic head, solids concentration, particle size and shape, slurry chemistry, temperature, and operating schedule before comparing models. Rubber lining can be a suitable wetted-part option for many abrasive slurries, but compatibility depends on the actual process conditions and the pump design. This guide provides a practical framework for preparing a specification and discussing options with a manufacturer such as RUIBANG.

This guide is for mine operators, process engineers, maintenance teams, and procurement professionals sourcing pumps for mineral processing duties. It is also useful for EPC contractors and distributors preparing technical inquiries on behalf of a project. I focus on selection questions that help turn a general request for a “rubber lined slurry pump” into a reviewable duty specification.
A slurry pump moves a mixture of liquid and suspended solids through a pumping system. In a rubber lined design, rubber is used to protect selected wetted areas from abrasive contact, according to the manufacturer’s construction. The pump still needs to be selected as a complete hydraulic and mechanical unit: casing, impeller, shaft arrangement, sealing system, drive, and supporting installation all affect suitability.
Rubber is not automatically the best choice for every slurry. Particle sharpness, impact, chemical composition, temperature, and operating conditions can affect lining performance, so material selection should be reviewed against actual process data. Where the slurry contains coarse or highly angular particles, or where chemical and thermal conditions are demanding, ask the supplier to assess whether rubber or another material is more appropriate.
Start by defining where the pump sits in the process, such as a sump, grinding circuit, flotation area, tailings line, or concentrate transfer point. Record the normal flow and head, as well as minimum, maximum, and any transient operating conditions that matter. Include whether the pump runs continuously, intermittently, or under changing production rates.
For example, an inquiry might describe a required flow of 120 m3/h and a calculated total dynamic head of 28 m. These are illustrative values only, not a recommended pump duty or a RUIBANG performance claim. The actual operating point must be confirmed from the system calculation and supplier selection data.
Provide solids concentration by mass or volume, slurry density or specific gravity, liquid composition, and the distribution of particle sizes. Include the largest expected particle, not just an average, and note whether particles are rounded, angular, fibrous, or prone to settling. As another illustrative inquiry detail, a maximum particle size of 0.5 mm may be useful only when it reflects measured or reliably estimated process data.
Also report pH, process temperature, and any chemicals or dissolved components that could affect wetted materials. If these values vary, give the normal range and the most demanding credible condition. I would avoid treating a single laboratory sample as representative when the feed changes across shifts, ore zones, or process stages.
Rubber lining is commonly considered when abrasion resistance and replaceable wetted protection are priorities. Its suitability depends on the compound offered, the pump’s construction, and the slurry’s chemistry and operating conditions. Ask the supplier to state which components are lined, what material option is proposed, and which application data support that recommendation.
Metallic wear parts or other material options may be considered where impact, temperature, chemistry, or particle characteristics make rubber less suitable. There is no universal material choice for all mining slurries. Compare the expected wear mechanism and maintenance plan rather than relying on a broad label such as “abrasive service.”
Impeller design, casing arrangement, shaft sealing, drive type, and installation layout should be reviewed alongside the liner material. The chosen configuration needs to meet the required flow and head without ignoring solids passage, suction conditions, access for maintenance, or available motor and power supply. Confirm whether the quotation includes a base, motor, coupling, guard, and other accessories required for the installation.

Ask for the proposed duty point and the performance information used to select the pump. Confirm that the stated head represents the system requirement and clarify how variations in slurry density or operating flow are treated. If the duty is not yet fully defined, request a preliminary review that lists assumptions and outstanding inputs instead of treating an estimate as a final selection.
Purchase price depends on the selected pump size and configuration, material choices, drive and accessory scope, and order requirements. A quotation should make clear whether it covers the pump only or a complete pump set, and it should identify any exclusions. I recommend comparing offers on the same duty and delivery scope rather than using unit price alone.
Minimum order quantities and production lead times can vary by model, customization, component availability, and current manufacturing schedule. Request a written quotation that states the validity period, delivery basis, packaging, payment terms, and estimated dispatch timing. For project schedules, confirm whether technical approval, drawing review, or customer-supplied requirements affect the timeline.
Request evidence relevant to the specific offer, such as dimensional information, performance documentation where available, material descriptions, and an itemized scope. Do not assume that a general product description confirms suitability for your exact slurry. A responsive supplier should be willing to identify information gaps and discuss them before you finalize the order.
One frequent mistake is sizing from an existing pump’s nameplate without checking whether the system or slurry has changed. Another is providing only flow and pipe diameter while omitting total head, solids data, chemistry, or suction conditions. These omissions can make supplier comparisons unreliable and may lead to a configuration that does not match the process.
It is also risky to choose rubber lining solely because the duty is described as abrasive. Abrasion is only one part of the material decision, and operating conditions can change the balance between wear, chemical compatibility, and impact. Finally, avoid comparing quotations that use different duty points or exclude different components; first normalize the technical and commercial scope.
RUIBANG supplies slurry pump solutions and can review an inquiry for a rubber lined slurry pump based on the information provided. To support a useful discussion, send the required flow and head, slurry composition and solids data, temperature and chemistry, operating schedule, installation details, and preferred delivery timing. If some values are not yet available, identify them as estimates so they can be treated as open assumptions.
For a quotation request, include photographs or drawings of the installation where available, along with the existing pump model if this is a replacement. Ask RUIBANG to confirm the proposed configuration, material basis, included scope, and information still needed before order approval. This keeps the evaluation focused on your application rather than a generic product description.
The best rubber lined slurry pump for a mining or mineral processing application is the one whose hydraulic duty, materials, and configuration are reviewed against the actual slurry and installation. Begin with measured or well-supported operating data, then compare supplier proposals using the same requirements and scope. Rubber lining may be a suitable choice, but its application should be confirmed rather than assumed.
Your next step is to prepare a duty sheet with flow, total dynamic head, solids concentration, particle characteristics, chemistry, temperature, operating pattern, and site requirements. Send it to RUIBANG for a technical and commercial review, and ask the supplier to document assumptions before you proceed with model selection or purchase.
