Model RX/RXA Slurry PumpsHeavy Duty, All-Metal Construction. Expressly Designed forHandling Abrasive Slurries at High Heads and Low Speeds.

Model RXA option provides improved wear life andease of maintenance with no change in performance.

Benefits include:

• Redesigned cutwater to reduce wear.

• Tapered casing to liner fits for reduced wear.

• Confined O-Rings for extended liner life.

• Lifting lugs for safety and ease of maintenance.

HEAVY-DUTYBEARINGSBearings aremounted in singlehousing for accuratealignment.

DRIVE ENDDesigned for eitherdirect connection oroverhead V-belt drive.

OVERSIZED SHAFTHigh tensile steel shaft of rugged designhas machined shoulders for positivepositioning of bearings, easily withstandsshock loads and vibration. Removablehook-type sleeve protects shaft where itextends through stuffing box.

PACKING GLANDExtra deep stuffing box subjectto suction pressure only.

BALANCED-WEAR

IMPELLEREfficient design

assures even wearof the pressure-

balanced impeller,with large interior

clearance and heavywear sections.Exterior vanes

reduce liner wear.

EASY PART REPLACEMENTWater end designed with clamped

construction for ease in replacement ofparts without dismantling suction and

discharge piping. Special locking deviceholds end cover liner in domed end coverfor ease of disassembly and reassembly.

SHAFT SLEEVEShaft sleeve fit and

impeller hub thread sealedfrom liquid being pumped.

DOMED END COVERDomed end cover construction

provides extra strength forhigh-pressure applications.

CASINGWall thickness of the sturdy

volute casing is increased atmaximum wear points.

Extensive wear-testing ofadvanced hydraulic designs

ensures uniform wearcharacteristics.

SUCTION DISCAND END

COVER LINERSExtra thick

renewable liners forsuction disc and end

cover are standardon RX pumps.
