A31P - A33P

Product catalog summary

Applications: The A31P, A32P, and A33P range of mechanical drive pumps are suitable for various industries including surface treatment, chemical transfer, water treatment, paper industry, agribusiness, cosmetics, fish farming, and metallurgy.

Features and Advantages: The pumps are constructed with an injected plastic body made of polypropylene, offering excellent resistance to acids and bases. They can handle a maximum fluid temperature of 75°C. The centrifugal closed impeller and diffuser design ensures high efficiency, with a maximum flow rate of up to 57 m³/h and a maximum manometric head of up to 50 meters. The impeller is back-balanced on the drive shaft with a rotating ring, and the carbide/carbide seals provide high wear resistance. The integrated motor design reduces the overall dimensions of the pump.

Technical Specifications: The pumps are equipped with a 230/400 V 3-phase motor, operating at 50 Hz or 60 Hz upon request, with a speed of 2,900 rpm. They feature serial-mounted carbide/carbide seals, with other seal types available upon request. Standard inlet/outlet options include union nuts or flange fittings.

Pump Models:

A31P: Motor power of 4 kW, maximum output of 40 m³/h, and a maximum head of 40 meters.
A32P: Motor power of 5.5 kW, maximum output of 52 m³/h, and a maximum head of 32 meters.
A33P: Motor power of 7.5 kW, maximum output of 57 m³/h, and a maximum head of 50 meters.

All models have a maximum fluid temperature of 75°C and use EPDM or FPM gaskets.

Performance Graphs: The document includes performance graphs illustrating the yield percentage, NPSH (Net Positive Suction Head), and manometric head relative to the output in m³/h for each pump model.

Dimensions: Detailed dimensions for flange fittings and union nuts are provided for each pump model, ensuring compatibility with various installation requirements.
