Technical Description

Centrifugal Seal ArrangementCentrifugal Seal ArrangementCentrifugal Seal ArrangementCentrifugal Seal ArrangementCentrifugal Seal ArrangementThe expeller generates a high head and works inconjunction with expelling back vanes of the impeller toprovide a highly effective seal against positive inlet headswithout gland leakage. Abrasion resistant materials ensurewear life equivalent to the pump. Three rings of grease-lubricating packing, seal the pump while stationary.

Even Wear DesignEven Wear DesignEven Wear DesignEven Wear DesignEven Wear DesignCase and impeller are matched for minimum hydraulicturbulence for longer and more equally distributed impellerand case wear life.

Impeller DesignImpeller DesignImpeller DesignImpeller DesignImpeller DesignRadial or partial mixed flow main vanes reduce hydraulicshock losses at the suction eye. Large diameters andstrategic mass distribution permit high head and highperformance at slow speeds without the sacrifice ofefficiency.

ANSI / Metric Flanges as RequiredANSI / Metric Flanges as RequiredANSI / Metric Flanges as RequiredANSI / Metric Flanges as RequiredANSI / Metric Flanges as RequiredSuction and discharge flanges are split on all HM and MMpumps for optional flange configurations, ease of pipeconnection and alignment.

Standard Expeller Shaft SealUsed for no product dilution against positive suction headwithout leakage. The standard pump has a primary highperformance hydrodynamic expeller dry seal which sealsthe shaft when the pump is running. A secondary, packedgland seal stops leakage when the pump is not running.

Low FlowUse for suction conditions not suitable for centrifugalsealing when product dilution needs to be minimized.One ring of packing is placed in front of the lantern ring.

The expeller is not used on flushed seal assemblies.

Metso Slurry Mechanical SealUsed for zero stuffing box leakage or product dilution.Available as single slurry type mechanical seal or doublemechanical seal with external barrier fluid required. It ispossible to use dead-end flush on the double seal.

Shaft Sealing Options

Full FlowUse for suction conditions not suitable for centrifugalsealing when product dilution is not important. Full flowprovides the longest packing wearing life. The lanternring is placed in the bottom of the stuffing box while thebox is protected by a lip seal to avoid damage fromtemporary concentrate variations.

Combined Low Flow / Full Flow Stuffing Box DesignStuffing Box can be built for either low or full flow optionsby changing the arrangement of the lantern ring, packing and flush connections.

Optional Double Adjustment Features

Optional Back and Front Pull-out Design

The total impeller wear clearance adjustment is a patenteddesign feature. The procedure of closing the back andfront impeller clearances permits constant perfomanceof the pump throughout the normal wear life of allcomponents. This simple operation is illustrated in the twosteps shown below and can be performed in minutes onsite pump without disassembling the pump.

Back clearance

Centrifugal seal clearance

Step 2. Adjust impeller front-side clearanceImpeller front clearance is made by removal of casinghalf-shims and retightening casing bolts. This also acts as avisusl wear indicator. The entire power fame moves forwardto close the impeller front-side clearance.Once all the shims are removed, the pump can still beoperated as a single adjust build.

Back Pull-out DesignFor normal routine inspection or repair, the bearing frameand rotating element can be removed as a unit. Impeller,piping and gland seal component renewal can be carriedout rapidly.

Front Pull-out DesignFor casing only renewal, or if back pull-out is not convenient,the front pull-out feature can be used after pipeworkremoval.

Step 1. Adjust impeller back-side clearanceImpeller back clearance and centrifugal seal adjustmentis achieved by adjusting the screw on the bearing cylinderhousing. The bearing cylinder housing, shaft and impellermove back in order to close the impeller back clearance.Double adjustment can also be made on low flow, fullflow and mechanical seal arrangements.
