ARMSTRONG SERIES 4270 PUMP- THE QUALITY PUMP WITH GREAT FEATURES

Are you looking for Motor Mounted Centrifugal Pumps? The best one for you would be Armstrong series 4270 pump. Let us have a look at the different amazing features the pump has to offer:

• Volute: The volute is radially split and can be left in the line while carrying out pump servicing tasks. You can eliminate unnecessary disconnecting of pipes. The venting, draining and gauge connections are made possible through tapped openings.
• Impeller: The impeller has high strength and is designed in such a way that axial thrust reduces to minimum. This ensures smooth performance and makes the pump durable.
• Motor: The bearings in the motor are permanently-lubricated bail bearings that are sufficiently rated to make space for radial loads of the impeller and also the residual hydraulic thrusts. The frequency of rotation is 3600 rpm.
• Mechanical Seal: This seal prevents the spilling of liquids. It is self-lubricating in nature. There is a carbon face that rotates against a static ceramic seat. It provides a positive sealing up to the full design pressure.
• Adaptor: The adaptor is cast with aluminum die and provided with integral support foot thus giving it a lightweight structure and long-lasting functionality.
• Shaft: The motor shaft of the pump spreads through the impeller, thus ruling out the possibilities of an intermediate bearing bracket and giving rise to a close coupled design.
• Back Pull-out Design: Due to this design, the pump does not require to break piping connections while servicing the pump. To remove the motor from the volute along with the bracket and impeller attached to it, the volute screws are provided.

Utility: The pump finds great utility in different spheres. You can use it cooling towers, HVAC and also for general purposes.

Now, let us see what all materials are used for manufacturing the different parts of the pump:

• The volute is made of cast iron or bronze depending upon the type of pump under consideration.
• Its cap screws are made of steel.
• The impeller is made either using PEI resin or bronze.
• For the other parts such as insert, seal, bellow, L-cup, retainer and spring, materials such as carbon, viton, ceramic, stainless steel are used.

If you need a pump to serve the different purposes mentioned above, the Armstrong series 4070 pump will be the perfect one for you.
