With so many stainless steel bars options in the market, it can be hard to choose the right stainless steel bars for pumps shafts.

Industrial pumps require a stainless steel shaft with tight dimensional & straightness tolerance that can vary in shape depending on the application. Many pumps industry are facing an issue of high-quality stainless steel bars for shafts.

Vishwa Stainless Pvt. Ltd. has manufactured a special range of stainless steel bright bars called Pump Shaft Quality (PSQ) bar which are peeled, ground and polished shafts used in pump applications. Our newly developed PSQ bars have tight dimensional & straightness tolerance. In our PSQ bars diameter tolerance & best surface finish achieved with the help of grinding and followed by polishing.

While manufacturing PSQ bars we take care of each and every aspects which require to develop PSQ bars. Below are top 4 things which make our stainless steel bars a high-quality PSQ bars.

#1. Heat Treatment:

Heat treatment process is the heart of any steel making process. By the heat treatment process, material achieved uniform microstructure and mechanical properties. We have in-house heat treatment facility with a narrow range of temperature process. Due to the heat treatment process, our PSQ bars are most preferable in critical applications.

#2. Strength:

High-speed rotation of bars with a heavy load can generate high stress on the material and it may cause accident also. Our exclusive range of PSQ bars have a specified range of yield and tensile strength varies depending on grades.

#3. Tolerance:

In PSQ bars tolerance should be perfect from all point of views. When a shaft is rotating at high speed any deviation in the bar from specified limit can cause a failure.

– Straightness: 0.005 TIR (total indicator run-out) in 1st 3FT. of bars. 0.0015 TIR in next each FT. of bars.

– Diameter:

DIA. RANGE TOL. LIMIT <1 “ ( 0.00″ , +.002″) 1″ – 1.437″ ( 0.00″ , +.0025″) 1.5″ – 4″ ( 0.00″ , +.003″)

– Ovality: Acceptance limit is 50 percent of diameter all tolerance

#4. Packing:

Packing system matters the most in PSQ bars. It should be delivered in an appropriate way to the customers. Vishwa Stainless Pvt. Ltd. has special boxing for PSQ bars to ensure the protection for the finish and straightness of material during transportation and handling. All bars are individually wrapped in cardboard tubing and packed in wooden boxes before dispatching to the client.
