Description

The pump impeller is the rotating component in the pump that directly transfers the energy from the motor into the fluid being pumped. Pump impellers are classified as one of three types: Open impeller, semi-open impeller, or closed impeller. Their classification is based on whether they have a protective shroud or not.

Impeller type	Details	Application
Closed impeller	The construction of enclosed impellers includes additional back and front walls on both sides of vanes that enhances its strength. The efficiency of closed impellers is higher. But the more complex design leads to higher production costs than open impellers.	They are generally used in large pumps, centrifugal pumps and clear water applications.
Semi-open impeller	The semi-open impeller is very similar in its design to the closed impeller. The one major difference is the absence of the front shroud. The additional back wall, giving it more strength.	The semi-open impellers or semi-closed impellers are usually used with liquids or mixed solid-liquid products. Mainly, they are well suited for medium sized pumps.
Open impeller	An open face impeller doesn’t have a back or front wall, only have blade and blade reinforcement. Without walls making open impellers slightly weaker than closed or semi-closed impellers. The number of open impeller blades is 2~6.	Open impellers are generally operating at higher tip speed and easier to clean and repair. Open impellers are usually used in smaller pumps and pumps that handle suspended solids and less to clog.

Impellers are made from a variety of materials, including stainless steel, cast iron, bronze, aluminum, austenitic stainless steel, titanium, etc. When you choose the suitable material for pump impeller, you should think about the following several factors, strength, fluid compatibility, abrasion resistance, environmental conditions, type of liquid being pumped, casting and machining properties, etc.

Baoding Guokun, an ISO 9001:2008 certificated investment casting and machining factory, can offer you the most suitable material as per your pump’s requirements. And with 25 years casting experience, we can produce the custom pump impellers with the suitable cast metal and casting process.

Stainless steel pump impeller: Stainless steel is the most common pump impellers material because of its anti-corrosive, anti-heat and anti-contamination properties. The Baoding Guokun stainless steel casting pump impellers are made as investment casting process, or lost-wax casting process that results in a significantly improved surface finish & casting tolerance and impeller quality than other sand cast bronze pump impellers.

Cast iron pump impeller: gray iron pump impeller, ductile iron pump impeller. Sand casting process can be used to produce the cast iron pump impeller. The cast iron pump impeller is competitive for stainless steel pump impeller and copper based alloy pump impeller.

Aluminum bronze pump impeller: Baoding Guokun can use sand casting process or investment casting to aluminum bronze pump impeller. The material is UNS C87800, UNS C95200, UNS C96400, UNS C95700, UNS C93700 impeller. The more information of C95200 bronze pump impeller is as follows:

C93700 Aluminum Bronze
Chemical Composition		Mechanical Properties
Cu%	78-82	Tensile strength	241 MPa Min
Pb%	8-11	Yield strength	138 MPa Min
Sn%	9-11	Elongation	6%

High-Leaded Tin Bronze sand casting pump impellers

Sand casting: Sand casting process is an industrial metal casting process that involves creating a mold from sand and pouring molten metal into it, generally used to cast the shaped parts of nearly any design, including large parts and those with internal passages. Baoding Guokun can produce various sand cast parts in cast iron, ductile iron, gray iron, low-carbon steel, mild steel, alloy steel for pump, valve, agriculture, railway, road, forklift, tillage, mining, automotive, medical, food, and aircraft, etc
