HERMETIC-Pumpen’s new single stage standardised chemical canned motor pump available from Renroc Group

Supplier News

HERMETIC-Pumpen has recently released their newly developed single stage standardised chemical canned motor pump in the HCN/HCNF range.

HERMETIC-Pumpen is represented in Australia by Renroc Group (Pumps & Engineering) Australia and is one of the world's leading manufacturers of canned motor pumps without shaft seal, suitable for use in industries such as refinery, petrochemical, chemical, energy and refrigeration.

The newly developed HCN/HCNF range of chemical canned motor pumps has been specifically designed for demanding applications. These chemical pumps are designed for aggressive, inflammable, toxic, and highly volatile liquids, solvents and other substances and are also suitable for use with liquid gases, for example ammonia, Freon, propane, and carbon dioxide.

The most recent development is a single-stage standardised chemical canned motor pump in accordance with EN 22858 / ISO 2858. The area of application for liquids covers a temperature range from –120°C to +120°C. Pump performance lies between 6kW and 41kW, with a maximum flow rate of 230m³/h and a maximum head of 140m.

The chemical canned motor pumps feature an integrated monitoring system for the rotation direction (ROMi) which is firmly moulded in the terminal box. A thermistor (KL180) secured in the winding ensures efficient protection of the motor. Additionally, HERMETIC provides a temperature monitoring unit using a T30 thermostat or PT100.

These canned motor pumps also feature hydrodynamic slide bearings made from tungsten carbide/silicon carbide (W5/SiC30) combination which is particularly wear resistant and low maintenance. A service life of eight to ten years is not uncommon with these motor pumps.
