R-Series

The engineered severe duty submersible slurry pump customized for the world’s most demanding abrasive and corrosive applications.

Rugged. Reliable. Relentless.

Overview

  • 11 different liquid end sizes (2″-8″ discharge with low, medium, high head options)
  • Trimmed impellers and several motor speeds to hit specific duty points
  • Various materials of construction for castings, machined parts, and hardware
  • Liquid temperatures up to 194F / 90C
  • Optional agitator and discharge elbows
  • Several mechanical seal and motor configurations
  • Castings and machined parts made in the USA
  • Assembled pump coated in ErgonArmor Novocoat SP2000W for superior protection 

Liquid End Features and Options

Casings feature vent holes and impellers have pump out vanes to expel slurries from the mechanical seal area.
Casings are drilled and tapped directly. No inserts are used which can corrode and break apart.
Shaft extensions (17-4 PH standard) with mixer agitators for higher solids concentrations. Agitators are secured by NordLock washers.
Impeller diameter and keyway with radius are precision machined via wire EDM .
Pump stands are cast for high strength. Standard material is 316 stainless for corrosion resistance. Other materials are available.
Pump discharge and long radius elbow flanges are ANSI B16.5 150# flat face. Elbows are available in 2", 3", 4", 6", 8" and in several material options.

Material Options

These material options can apply to pump castings (casing, impeller, suction/motor covers, agitator, elbows), machined parts, hardware, and motor shafts. Castings and machined parts are proudly made in the USA.

John Crane Type 5840 Slurry Seal

The 5840 seal is an outboard cartridge seal for ABB Baldor submersible motors only. It is used in conjunction with a single John Crane Type 21 internal seal (carbon/ceramic faces) in the motor oil chamber. This provides for a tandem seal arrangement with two independent seal systems. This is the most robust seal design offered with higher pressure and radial runout allowances with minimal exposed parts.

  • 2205 duplex stainless construction standard (2507 super duplex and C276 optional)
  • Silicon carbide seal faces
  • Encapsulated spring
  • Primary ring secured by set screws
  • Secondary ring secured by anti-rotation pin
  • O-ring fits
  • Can be used on motors for UL Listed Cl. I Div. I Groups C & D locations
  • Seal can often be repaired vs. replaced for lower maintenance cost

Type 5840 outboard slurry seal with pinned stationary mating ring. Single Type 21 inboard seal in oil chamber with 2 moisture probes for leak detection.

Internal Double Slurry Seal

Both EIM and ABB Baldor motors can use this seal configuration. It is a back-to-back double seal configuration where two sets of faces share a single spring. The entire assembly operates in the motor oil chamber and does not see the process fluid. This seal is also protected by a lip seal as the first barrier of protection. This seal is great for less severe applications and is more cost effective than the 5840.

  • EIM motors use Eagle Burgmann ED560 with silicon carbide lower (process) faces and carbon ceramic upper faces
  • EIM motors carry FM Approval for Cl. I Div. I Groups C & D hazardous locations
  • ABB Baldor motors use a John Crane Type 21 double seal with tungsten carbide lower faces and carbon ceramic upper faces
  • Stainless steel (316 and 304 construction) with fluoroelastomer bellows
  • O-ring fits for stationary faces
  • Lower stationary face is further secured via anti-rotation pin
