Spare Part

I. Impeller

The function of the impeller is to directly transfer the mechanical energy of the prime mover to the liquid to increase the static pressure energy and kinetic energy of the liquid (mainly increase the static pressure energy).

The impeller generally has 6 to 12 backward curved blades.

There are three types of impellers: open type, semi-closed type and closed type.

The open impeller has no cover plate on both sides of the blade, which is simple to manufacture and easy to clean. It is suitable for conveying materials containing a large amount of suspended solids. The efficiency is low and the liquid pressure is not high; the semi-closed impeller has no cover on the suction side. There are cover plates on the other side, which are suitable for conveying materials that are easy to precipitate or contain particles, and the efficiency is also low; the closed impeller has front and rear cover plates on both sides of the impeller, which has high efficiency and is suitable for conveying no impurities. cleaning liquid. Most of the general centrifugal pump impellers are of this type.

The impeller has two suction modes: single suction and double suction.

II. Pump Casing

The function is to seal the impeller in a certain space, so that the liquid can be sucked in and pressed out by the action of the impeller. The pump casing is mostly made into a volute, so it is also called a volute. Due to the gradual expansion of the cross-sectional area of the flow channel, the high-speed liquid thrown around the impeller gradually reduces the flow rate, so that part of the kinetic energy is effectively converted into static pressure energy. The pump casing not only collects the liquid thrown out by the impeller, but is also an energy conversion device.

IIIShaft seal device

The function is to prevent the liquid in the pump casing from leaking along the shaft or the outside air from leaking into the pump casing.

Commonly used shaft seals include packing seals and mechanical seals.

Fillers are generally oil-impregnated or graphite-coated asbestos ropes. The mechanical seal mainly relies on the relative movement of the end face between the movable ring mounted on the shaft and the static ring fixed on the pump casing to achieve the purpose of sealing.

Our company can produce slurry pump spare parts, which are widely used in mining, metallurgy, coal, electric power, dredging and other sectors of the national economy. Products are sold to South America, Africa, Southeast Asia, Russia and many other countries and regions. Our products have won unanimous praise and the market.

The main components in the pump are the housing, impeller, back plate, shaft and shaft seals and motor adapter.Pumps with replaceable spare parts and components can have an unlimited lifespan. A high-quality custom mud pump with replaceable parts can last a lifetime, so it should be considered a very reasonable long-term investment.

  • Volute Liner of slurry pump enhance the efficiency of slurry pumps by reducing the turbulence and minimizing the recirculation losses. This results in increased pumping capacity and reduced power consumption.

  • Slurry Pump Volute with Impeller is one of the key components of a centrifugal pump. It plays a crucial role in the transportation of various liquids, slurries, and solids in many industries, including mining, power generation, and chemical processing.

  • We, DePump, are the manufacturer for slurry pumps and spare parts. After years technical updated, our slurry pump spare parts could be totally exchanged with the original slurry pump spare parts. Not only for the wearing parts, like, impeller, volute, throat bush, FPL insert, shaft, sleeves, but also the Orings, washers, gland packings, even bolt and nuts.
