Product introduction

The customized Expeller Ring is one of the main slurry pump accessories products, usually made of metal or wear-resistant rubber materials, used to reduce the pressure inside the pump, to prevent liquid or slurry media from invading the pump shaft seal.
The Expeller Ring is an accessory located at the shaft seal of the pump.  Its function is to press the liquid or slurry in the pump to the feed port of the pump by rotating, so as to effectively reduce the pressure inside the pump and reduce the leakage of the medium.  This helps extend the life of shaft seals and bearings and reduces maintenance costs.
The purpose of these OEM slurry pump accessories in China during the operation of the pump is to reduce the impact of the environment on the shaft seal, reduce the risk of leakage, and improve the reliability and operation efficiency of the pump equipment.

Production capacity

The total design and production capacity of our factory is 10,000 units (sets) per year, and we can produce 2,000 tons of various high-chromium alloy castings annually. The production area currently includes the following production zones. Namely:casting workshop, heat treatment workshop, machining workshop, metal forming and welding workshop,assembly and painting workshop, spare parts warehouse and finished parts warehouse; Two centers:quality inspection and analysis center and the overall hydraulic test center. 

Our products are mainly made of high-chromium wear-resistant white cast iron such as A05, A07, A49, A33, etc. The product development and process formulation all adopt CFD and CAPP new technologies. All castings use resin sand molding and newly introduced lost foam casting technology, which can pour 8-10 tons of castings at one time. The heat treatment workshop has two 20 cubic electric resistance heat treatment furnaces, and the machining shop has two large vertical lathes of 4.2M and 4.5M and more than 20 other types of machine tools. In addition,there are various types of hoisting equipment,metal cutting and welding equipment,impeller level tuning equipment,molding equipment,sandblasting polishing equipment.

Our main products includes a full range of slurry pumps, desulfurization pumps, gravel pumps, dredging pumps, foam pumps, chemical process pumps, PU rubber slurry pumps, and other dozens of varieties, hundreds of models.Widely used in mining (mineral processing), metallurgy, coal, power plant, flue gas desulfurization, silt dredging, sewage treatment industries, chemicals, municipal and environmental protection and so on.
