Orson® high pressure slurry pump is a kind of the Horizontal centrifugal slurry pump. They are suitable for conveying abradability and corrosive slag slurry and is widely used in metallurgy, mining, petrol, chemical industry, coal, electric power, transportation, building material and municipal services. Its structure is very suitable for working environments with high transmission flow, high lift and high pressure.

The flow rate range of slag slurry with

▲ High concentration and high corrosion property is 40-80%.

▲ Medium concentration and medium corrosion property is 40-100%.

▲ Low concentration and low corrosion property is 40-120%.

Cost Savings.jpg

● Cost life effective.

● Replacement parts are dimensionally interchangeable with the Warman HH series.

● Reduced stock holidng due to extended service life.

● Highly resistant to swelling from chemical attack.

● Orson® high pressure slurry pump has increased slurry pump wet parts end life up to four and half times.

● The cost of rubber or steel parts to run 3375 hours was $9600. the mine has saved $18125 on just one pump in 4.5 months.

The structure and characteristics of high pressure slurry pump

The structure and characteristics of high pressure pump (2)

▲ The large diameter and Short cantilever ensure the rigidity of the shaft, which is suitable for high power and harsh working conditions.

▲ The hardened stainless steel shaft sleeve has O-rings at both ends to protect the shaft from abrasion and corrosion.

▲ The front and rear cover plates of the impeller have secondary blades, which can reduce backflow and seal pressure.

▲ The high pressure slurry pump body and the pump cover are made of ductile iron with reinforcing ribs, which ensures the ability to 

withstand high pressure.

▲ The flow parts are made of a variety of high chromium anti-wear alloys, which have the characteristics of wear resistance, corrosion resistance, impact  resistance and so on, greatly improving the service life of the pump.

▲ Different impellers can be selected according to different working conditions.

▲ The outlet position of the high pressure slurry pump can be installed and used by rotating eight different angles as required.

▲ There are two different lubrication methods for bearing components, and appropriate lubrication methods should be selected according to different working conditions.

Sealing Form.jpg

▲ Packing seal: The most widely used sealing form, through the front water seal ring continuously inject a certain pressure of clear water into the packing, to prevent the slurry leakage in the pump, for not suitable for sealing with the secondary impeller, stuffing seal is usually used. The packing sealing structure is simple and the maintenance is convenient.

▲ Mechanical Seal: Used when sealing requirements are relatively high. Especially in some chemical and video fields, not only sealing is required, but also additional components are not allowed to enter the pump chamber.

▲ Secondary impeller seal: Through the impeller acting force of a reverse centrifugal force, prevent the slurry from leaking out. The secondary impeller seal has the advantages of no need of shaft seal water, no dilution of slurry and good sealing effect. Therefore, this sealing form can be considered under the condition that dilution of slurry is not allowed.

Orson pump is the high pressure slurry pump supplier and manufacturer in Hebei. Since 1980s, Orson pumps has been engaged in the research and development, production and sales of Sludge pumpsSlurry Pumps, Warman & Weir Pumps, which can provide customers with overall solutions.
