Large Split Case Pumps package for iron ore mining process water dam


Dynapumps had the pleasure of working on seven large horizontal split case pump packages for an iron ore mining project at their process water dam. Each pump system utilised a Grundfos LS 800-600 pump, coupled to a WEG MGF500D electric motor, each producing 1200kW of power. 3 of the 7 pumps are being utilised for the Scrubbing Process Water Feed, and are designed to handle up to 6000m3/h of flow at a total dynamic head of 50 metres, whilst the other 4 are being utilised for the Desands Process Water Feed, designed to handle 5000m3/h at a TDH of 62 metres.

This enables a flow (in parallel) of 12000m3/h for the two Desands pumps, with the third acting as a standby, and a flow of 15000m3/h for the three Scrubber Pumps, with the remaining pump, also acting as a standby.

Dynapumps team
Dynapumps was responsible for the design and manufacturing of the large base frames that the equipment sits on, and all fabrication was completed in-house by our talented boilermakers. The motor stool design allows it to be filled with concrete ensuring stability on-site. Mating spools were also provided to ensure that the pump suction and discharge connections were suitable for the site requirements.
Vibration and temperature sensors were utilised on both the pumps and motors, with all connections feeding back to a custom-built junction box, fully designed and assembled by Dynapumps.

Our commissioning team is preparing to assist with the startup of the pumps on-site and will be on hand to provide knowledge and guidance through the commissioning process.
