Trash Hog IIA Full Range of Product Features

External Impeller AdjustmentContinuous high performance

maintained by simple adjustment.Absolutely no shims required.

Industrial Duty Power EndProvides rigid shaft support. Ampleoil volume results in cooler running

bearings for extended life.

High Strength Stainless SteelTapered Shaft

Maximum strength and corrosionresistance. Tapered impeller fit

facilitates easy impeller removal.

Silicon CarbideMechanical SealHard faces provide

substantially higherresistance to wear. Carbon/

ceramic seal is optional.

Back Pump-Out Vanes and RearImpeller RingReduces seal chamber pressure and axialthrust for extended bearing and seal life.Prevents solids from entering sealchamber. Close radial clearanceeliminates need to shim behind impeller.

Heavy Vaned Open ImpellerDesigned for superior performancein toughest solids handlingservices.

Renewable WearplateReduces maintenance costs; allowsrunning clearances to bemaintained for maximum pumpingefficiency and priming capability.

Class 125 FlangesStandard on suction anddischarge for positive sealingin all industrial services.

Replaceable Elastomeric CheckValveWith integral blow-out disc –provides for instantrepriming while preventingover-pressurization of casing.

Check Valve CoverplateSimplifies check valve replacementand facilitates inspection ofcheck valve and impeller withoutdraining pump.

Back Pull-Out DesignComplete power end with seal chambercan be easily removed from casing withoutdisturbing suction and discharge piping.Easy to sling power end makes pull-outsafe and simple. No need for special tools.

Ligthweight Clean-Out CoverMaintenance-friendly cover allowssafe and easy access to removeany debris.
