HVAC Pumps

Split Coupled Vertical In Line Pumps: Single stage, single or double suction type, with pump characteristics which provide rising heads to shut off.

Vertical In-Line pumps: being integral components of the pipework, eliminate need for inertia bases, inertia base springs, flexible pipe connectors, field grouting and alignment. Pipe hangers, sized for the weight of pump, piping and fittings, are the only supports required. Pipe stools, with vibration isolating pads, may be installed under each pipe leg. We can provide Long Coupled or closed coupled configuration.

Horizontal Split Case: Provide Horizontal Split Case pumps, single stage, double suction type, with pump characteristics which provide rising heads toshut off. Pump Casing – Cast iron, axially split, with 15°angle tilted parting to allow for lower NPSH requirements and to minimize pump dimensions. Suction and discharge connections, located in the lower casing, shall be flanged and of sizes indicated in the schedule and shall be drilled and tapped for gauge connections. Suction and discharge connections shall be on the same elevation. The top of the casing and the rotating assembly shall be removable without disturbing the piping connections.

End Suction Pumps: Long Coupled End suction pump shall be single, end suction type with radially split, top centre-line discharge, self-venting casing. The casing-to-cover gasket shall be confined on the atmospheric side to prevent blow-out possibility. Closed Coupled Single stage, single end suction, motor mounted centrifugal pumps, with risinghead characteristics to pump shut off

4300 Vertical In-Line

Armstrong innovative 4300 Vertical In-Line pump realises 60% savings in space compared to base mounted pumps. The split coupled design allows for the replacement of the mechanical seal without costly removal of the motor or pump from the piping.

 Design Features

  • Best First Installed Cost – Vertical In-Line pumps, being integral components of the pipework, eliminate need for inertia base springs, concrete plinths, flexible pipe connectors, and alignment.
  • Low Maintenance cost – an external seal allows rapid changing of the seal without the need of removing the whole rotating assembly.
  • Split coupling – the split coupling allows the seal to be changed without removing the motor.
