CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
A pump unit is the core mechanical assembly of a water pump system, consisting of an impeller, casing, shaft, and seals. It converts mechanical energy into hydraulic energy to move fluids. It is a component, not a complete pump set, and is used in machinery and equipment manufacturing.
Reference ranges include flow rates from 1 to 100 m³/h, heads from 5 to 200 m, operating pressures from 1.0 to 1.6 MPa, and temperatures from -20 to 120 °C. Speeds for 50 Hz motors are 1450 to 2900 rpm, with efficiencies of 60-85% at BEP. These are directory references and must be confirmed for the specific model.
Materials on file include cast iron, stainless steel, and bronze. For wetted parts, stainless steel grades 304, 316, and 316L are referenced. Material selection depends on the fluid and application; always verify with the manufacturer.
Standards referenced include ISO 9906 for hydraulic performance, IEC 60034 for motor speeds, ISO 1940 for balancing, ASTM A743 for stainless steel castings, and EN 1092-1 for flanges. These are verification references, not proof of compliance. Confirm with the supplier.
