GRUNDFOS HS HORISONTAL SPLIT CASE tHE GRUNDFOS GIANtMAxIMUM FlOw FOR MUltIplE ApplIcAtION AREAS

GRUNDFOSHS HORISONTAL SPLIT CASE

The Grundfos HS Horisontal Split Case is the giant in the Grundfos product range. It combines double suction ports with high flow and in-line pipe connection.

The HS Horisontal Split Case virtually eliminates radial loads by hydraulically balancing the liquid within its casing and it offers benefits like improved efficiency, minimised vibration, extended seal and bearing life and low noise levels.

HS HORISONTAL SPLIT CASEINtRODUctION

The split case is characterised by its ability to virtually eliminate radial loads by hydraulically balancing the liquid within the casing. This balancing ability is made possible by the unique double volute construction, which provides two individual volute passageways to guide the flow out of the impeller and into the discharge. Moreover, the split case provides the double suction impeller, which extends the life of the pump by neutralising the axial forces. The double volute and double suction construction has a number of great benefits:

• Improvedefficiency• Minimisedvibration• Extendedsealandbearinglife• Quietoperation

One man maintenanceThe split case pump features an exceptional bearing house/sealchamberconstruction,whichmakesitunnecessary to remove the top casing half in order to maintain the pump. That means that one person can easily access the bearing house and inspect seals, sleeves and bearings without the strain of heavy lifting. Consequently, the HS Horisontal Split Case guarantees a minimum of downtime because of the simplicity of its maintenance.

Broad band high efficiencyThe impeller design of the split case has been specifically matched to the casing of the pump in ordertoprovidebroadbandhighefficiency.Asaresult, the operating costs of the horizontal split case are reduced dramatically giving it a valuable low life cycle cost.

FlexiblegridcouplingThe flexible grid coupling is called the Rolls-Royce of couplings because it is able to compensate for misalignments to a certain degree. The flexible grid coupling comes as a standard feature in the HS Horisontal Split Case.

RenewableneckringsAllHsHorisontalsplitCasepumpsareequippedwithrenewable neck rings as a standard feature, which means that there is only wear on the bronze neck ring in the area between impeller and pump casing. This way the renewable neck rings help protect the costly casing.

DoublevolutedesignThe double volute eliminates radial loads by balancing pressure within the casing. Three major advantages are improved efficiency, minimised vibration and extended seal and bearing life.

Easy replacementThe bearings and shaft seals can be replaced without removing the upper casing, which makes maintenance simple and reduces downtime.

DoublesuctionimpellerThe definition of split case pumps includes double suction impellers. By directing flow into both sides of the impeller, axial forces are neutralised.

Clockwiseorcounter-clockwiseoperationAllHsHorisontalpumpsareselectedwitheitherclockwise or counter-clockwise rotation. If the opposite rotation is required, due to changes at the installation, the HS can easily be adapted with a simple change out of one component.

Life Cycle Cost (LCC) analysis is an objective standard that allows you to benchmark different pump solutions and suppliers, based on initial investment and the costs of installation, maintenance and energy.

By considering LCC when choosing your pumps, you can help reduce Co2 dramatically and thereby make an important contribution to the well-being of our planet.
