Apa Itu Pompa Lumpur Sentrifugal?
The PHH Series Centrifugal Slurry Pump is a high-head, heavy-duty slurry pump in the Pompa Changyu product line. It is specifically designed for pumping highly abrasive or corrosive slurries containing large particles and high hardness, and is capable of withstanding harsh environments where standard pumps are prone to rapid wear. In addition, we offer a series of chemical slurry pumps custom-engineered for applications involving fine particles and conditions requiring wear and corrosion resistance.
Unlike standard water pumps, the PHH uses high-chrome alloy wear parts (BTMCr27, BTMCr33) and a double casing design. The outer casing protects the pump, while the inner liner and impeller resist wear from coarse particles. When wear occurs, only the inner parts need replacement – not the entire pump.
Ini centrifugal slurry pump for mining delivers heads up to 97 meters and flows from 16.2 to 1008 m³/h, making it suitable for long-distance tailings lines dan high-head ash handling systems.
Advantages of the Centrifugal Slurry Pump
Longer wear life in abrasive service
The high-chrome alloy (BTMCr27, 28% Cr, ≥56HRC) provides outstanding resistance to erosion from sand, ore, ash, and tailings. In field applications, PHH liners and impellers last 1.5 to 3 times longer than conventional cast iron or steel pumps.
Reduced downtime and maintenance costs
The double casing structure with replaceable liners means you do not discard the entire pump when wear occurs. Only the inner shell and impeller are changed – a fast, low-cost field repair.
High head for long-distance pumping
With a maximum head of 97 meters, the PHH series maintains pressure over long slurry pipelines. It is a reliable high-head slurry pump for mill discharge, cyclone feed, and tailings return.
Flexible sealing and drive options
Choose a packing seal, an expeller (dynamic) seal, or a mechanical seal, depending on head, leakage limits, and site preference. Drive via direct coupling, V-belt, or hydraulic motor.

Slurry Pump Specifications
Bagian
The PHH Series features a modular, wear-resistant design. Below are its main structural components:
| Komponen | Material / Feature | Fungsi |
|---|---|---|
| Casing | Double layer (outer ductile iron + inner high-chrome liner) | Protects pump body; inner liner replaceable |
| Baling-baling | High-chrome alloy (BTMCr27, ≥56HRC) | Converts motor energy into slurry velocity and pressure |
| Liner (Volute) | High-chrome alloy or rubber | Directs slurry flow; absorbs wear from solids |
| Shaft & Bearing Assembly | Heavy-duty bearing cartridge | Supports rotor; ensures smooth, vibration-free operation |
| Seal System | Packing seal, expeller seal, or mechanical seal | Prevents leakage; choice depends on head and duty |
| Baseplate | Steel fabricated | Aligns pump and motor; maintains belt or coupling tension |
Note: This is the basic structure of the PHH slurry pump. There may be some variations depending on the pump size.
Slurry pump shaft seal
The shaft seal is one of the important mechanical components in a centrifugal slurry pump. We select the appropriate sealing type according to the site requirements！
There are three commonly used shaft sealing types:
Gland packing seal
The gland packing seal is the most common type of seal. It works by introducing shaft sealing water at a certain pressure and flow rate, which is evenly distributed through the front water sealing ring into the gap between the packing and the shaft sleeve, preventing slurry leakage from the pump casing.
Its functions include cooling, lubrication, and flushing. For multi-stage series pumps where an auxiliary impeller shaft seal is not suitable, a gland packing seal is used. The gland packing seal has a simple structure, is easy to maintain, and is cost-effective.
Auxiliary Impeller Seal
The auxiliary impeller seal mainly relies on the pressure generated by the auxiliary impeller, which rotates synchronously with the main impeller, to prevent slurry leakage. It is used in applications where dilution of the slurry is not allowed. Water sealing or grease lubrication can be used.
Segel Mekanis
The mechanical seal consists of a stationary face and a rotating face that are pressed together under mechanical and hydraulic pressure to prevent leakage. It provides the best sealing performance and is suitable for zero-leakage conditions. A low-pressure flush-type mechanical seal does not dilute the product. However, it has a high cost.
