The Hamworthy Pump range includes
As an official ASP (Authorised Service Provider) for Hamworthy Pumps in the UK, AVTPUMP can offer local support to all Hamworthy Pumps customers from our workshop locations. From pump supply, to pump servicing, pump repairs to pump spares, AVTPUMP provides support to all levels including to operators, shift technicians and project managers.
Drawing on our own vast experience in the pump industry and where needed the sharing of knowledge and expertise between AVTPUMP and pump partners like Hamworthy Pumps we are focused on ensuring that your pumps perform, keeping the rotating assets on your site at peak performance.
Centrifugal pumps are currently in use across a vast array of domestic and industrial processes. From supplying the water used in residential buildings to industrial applications like food, beverage, and chemical manufacturing, different types of centrifugal pumps are required to effectively meet pumping requirements.
The model CG single-stage centrifugal pumps are designed for long and reliable service life and are only manufactured in a vertical design. The pumps are radially split and the complete rotating element can be dismantled independently of the motor and piping connections. Model CG is noted for its robust construction and operating reliability and a unique hydraulic design gives a compact unit with modest space requirement and low weight of parts to be handled. The shaft runs in an amply dimensioned bearing of anti-friction type whereas the lower part runs in an over-dimensioned bush bearing.
NOTE: For casings and impellers various additional material options may be available on request. e.g. other grades of bronze, Duplex, Nodular Cast Iron, etc. For shafts various materials are available on request e.g. Monel, Super Duplex – UNS32760, etc. For driver options other transmission devices e.g. gear coupling available on request. Other coupling options are available on request.
Various mechanical seal options are available on request e.g. balanced seal, harden-faced seal faces, Hastelloy metals parts etc. For elastomers materials other options are available on request e.g. EPDM. Product lubricated sleeve bearing is available on request.
Advantages:
Long-established vertical between-bearings design. The pump is available as a tested bare-shaft replacement with its own bearings.
Applications:
Ballast, Fire, Fresh/Sea Water Cooling & General Service
A typical centrifugal pump setup is comprised of one or more impellers attached to a rotary pump shaft. This arrangement provides the energy required to conduct fluid through the pump system and the associated piping.
The impellers turning in sync with the pump shaft convert dynamic mechanical energy from the pump motor into the energy of moving fluids. While most of the energy derived from the motor will be converted to kinetic energy in the pumped fluids, a portion will be channeled as potential energy in fluid pressure calculated against gravity.
The operation cycle begins with the pump directing fluid into its suction ports and directing it onward to the inlet of its impellers. Rotating impellers then move the pumped liquids along their spinning vanes whilst simultaneously increasing the fluid velocity.
The “charged” fluid then leaves the impeller vanes and is conducted to a diffuser casing or pump volute where high fluid velocity generated from the impeller vanes is converted to high fluid pressure. Finally, the pressurized fluid is conducted to a discharge port or channeled to the next stage of a multi-stage pump system.
The major centrifugal pump variations include the following:
The major distinction between a radial and an axial centrifugal pump is in their orientation. By design, a radial centrifugal pump permits an outward motion of the liquid channeled through it. The pumped liquid is pressurized and exited through downstream piping. By comparison, axial pumps generate fluid motion via a lifting effect of their impeller vanes.
Centrifugal pump uses are common throughout a diverse range of domestic, commercial, and industrial markets. Examples of centrifugal pump applications include but are not limited to:
