Kenda KH(R) Series Slurry Pumps Key Features | High Wear-resistant Industrial Transfer Solutions

Engineered for the Toughest Abrasive Challenges

The Kenda Metal Lined Slurry Pump is a premier heavy-duty, horizontal centrifugal pump designed specifically to handle high-density, abrasive, and coarse slurries in demanding industrial environments. Built with a robust double-casing structure, this pump ensures maximum safety and operational reliability under high-pressure conditions.

Superior Wear Resistance with High-Chrome Alloy

At the heart of our metal-lined series is the interchangeable A05 High-Chrome Alloy (27% Cr) liners and impellers. Unlike standard pumps, our metallurgy is vacuum-cast to ensure zero porosity, providing exceptional hardness (HRC 60+) and resistance against particle impingement. This significantly extends the mean time between maintenance (MTBM), reducing your total cost of ownership (TCO).

Advanced Hydraulic Design & Versatility

Our engineering team has optimized the impeller vanes to provide the highest hydraulic efficiency without compromising wear life. The pump features:

• Replaceable Metal Liners: Precision-fit liners are bolted (not glued) for easy replacement and maintenance.

• Flexible Sealing Options: Choose from Expeller Seals (centrifugal) for waterless operation, Packing Seals, or customized Mechanical Seals for zero-leakage requirements.

• Multi-Stage Capability: Designed to allow multiple units to be installed in series for high-head, long-distance tailings disposal.

Built for Global Standards

Kenda pumps are engineered to be dimensionally interchangeable with leading international brands, making them the ideal choice for plant upgrades or as high-performance replacements. Whether you are managing mineral processing (copper, gold, iron ore), coal washing, or power plant ash removal, our metal-lined pumps deliver consistent flow rates and superior suction performance in the harshest pH environments.

Frequently Asked Questions (FAQ)

Q1: How do I choose between Metal Lined and Rubber Lined Slurry Pumps?

A: The choice primarily depends on the particle size and shape of your slurry.

• Metal Lining (High-Chrome  Alloy):  Best for handling large, coarse, or sharp particles and high-impact conditions  (e.g., primary mining or gravel). It offers superior hardness (HRC 60+).

• Rubber Lining: Ideal for fine particles (typically <5mm) and highly corrosive or acidic environments (pH 2-13). If your application involves heavy mining tailings or crushed ore with sharp edges, a Metal Lined Slurry Pump is usually the more durable choice.

Q2: Why is my pump impeller wearing out faster than expected?

A: Accelerated wear is often caused by three main factors:

1. Operating Away from BEP: If the pump operates too far from its Best Efficiency Point, internal turbulence increases, causing localized erosion.

2. Material Mismatch: The slurry's hardness might exceed the limits of the impeller alloy.

3. Cavitation: Insufficient suction pressure creates vapor bubbles that implode on the metal surface, pitting the impeller. Tip: Regularly adjust the impeller clearance to maintain high efficiency and      reduce backflow erosion.

Q3: Are Kenda Metal Liners interchangeable with other major brands?

A: Yes. Kenda slurry pumps are engineered to be dimensionally interchangeable with international industry standards. Our wet-end parts—such as impellers, volute liners, and throat bushes—fit seamlessly into existing pump casings of similar designs. This allows you to upgrade to Kenda’s high-performance A05 wear-resistant parts without replacing your entire pump system, significantly reducing maintenance costs.

Q4: How can I extend the service life of a High-Chrome Alloy Slurry Pump?

A: Proactive maintenance is key to longevity:

• Impeller Adjustment: Periodically adjust the  gap between the impeller and the throatbush to compensate for wear and maintain hydraulic performance.

• Seal Maintenance: Ensure the expeller seal  is properly lubricated or that the gland packing has the correct flow of cooling water to prevent slurry from entering the shaft sleeve.

• Avoid Dry Running: Never run the pump without  fluid, as this causes rapid heat buildup and can damage the mechanical seals or internal liners.

Q5: What is the maximum solid size a Kenda Metal Lined Pump can handle?

A: The maximum allowable particle size depends on the specific pump model and its discharge diameter. Generally, our metal-lined pumps are designed with wide internal passages to handle solids up to 50% to 80% of the discharge pipe diameter, depending on the particle concentration and shape. For specific spherical clearance data, please consult our engineering team with your slurry analysis.

Case Studies

Case Study 1: Improving Efficiency in a Coal Preparation Plant (Australia)

Industry: Coal Washing & Preparation

Challenge: An Australian coal plant struggled with high energy consumption and leaking shaft seals in their heavy-media circuit. They needed a reliable, high-efficiency solution that could integrate into their existing pipeline without costly modifications.

Our Solution: Kenda provided dimensionally interchangeable metal lined pumps with optimized Expeller Seals (Centrifugal Seals). This allowed the plant to operate without seal water, preventing slurry dilution.

Results:

Perfect Fit: 100% compatibility with existing piping, reducing installation time by 70%.

Energy Efficiency: The optimized hydraulic design led to a 12% reduction in power consumption.

Zero Leakage: The expeller seal eliminated the need for gland water, saving thousands of gallons of water daily.

Case Study 2: High-Head Tailings Disposal for an Iron Ore Project

Industry: Iron Ore Mining

Challenge: The project required transporting high-density iron ore tailings over a distance of 3km with a vertical lift of 60 meters. A single-stage pump could not handle the required head pressure.

Our Solution: Kenda engineers designed a multi-stage pump system using three 6/4D-MAH Metal Lined Slurry Pumps installed in series. The double-casing design of our pumps ensured they could safely withstand the high internal pressures of a multi-stage setup.

Results:

Steady Performance: The system maintained a consistent flow rate of 350 m³/h at the required pressure.

Durability: Despite the high-pressure environment, the metal liners showed minimal signs of wear after 4,000 hours of continuous operation.

Safety: The robust outer casing provided an extra layer of protection for onsite workers.
