MCR², MCR, MCR-M, MCU, AH, AHPP, WBH, AHF, LF and MF series. Start with pump size and duty to identify wet-end wear parts, shaft assemblies, seals and materials.
Use this page to identify Warman slurry pump spares, assess materials and prepare drawing-based supply. First narrow the selection by series, size, rotation, liner and shaft-seal configuration. Confirm manufacturing requirements using the nameplate, full model, serial number, drawing, general arrangement or a traceable used part.
The table lists series, sizes, flow rates and heads relevant to spare-part selection, using Weir's public product pages as the source.
| Series and Standard Models | Published dimensions / performance | Typical Applications | Key Spare-Part Checks |
|---|---|---|---|
| Warman MCR² / MCR / MCR-M / MCU | Discharge 125–760 mm; flow up to 12,500 m³/h; head up to 55 m | Mill discharge, cyclone feed and highly abrasive slurry circuits | Full series designation, discharge size, rotation, liner type, impeller and throatbush configuration |
| Warman AH / AHPP | Published combined range: discharge 100–450 mm; flow up to 8,600 m³/h; head up to 73 m | Continuous transfer of highly abrasive, dense slurry; AHPP for higher pressure and series operation | Pump model, size code, pressure configuration, metal or elastomer wet end and shaft-seal type |
| Warman WBH | Discharge 25–300 mm; flow up to 3,000 m³/h; head up to 73 m | Heavy-duty process pumping, slurry transfer and mill discharge | Full model, size, impeller, throatbush, volute liner, shaft seal and installation orientation |
| Warman AHF / LF / MF | Discharge 50–550 mm; flow up to 8,000 m³/h | Aerated froth, flotation froth and slurry with high air content | Series, size, liner material, impeller design and presence of a continuous air-removal system |
Impellers, throatbushes, volute liners, side liners and expellers are arranged by installation position.OEM images refer only to the products shown.
Impeller
The impeller transfers energy directly to the slurry and is one of the wet-end components most exposed to abrasion, erosion and localized corrosion. Confirm vane design, diameter, thread or shaft-end connection and rotation against the complete pump model.
View the component guide →
Throatbush / Throat Bushing
The throatbush sits at the impeller inlet, controls the front clearance and withstands erosion from incoming high-velocity slurry. During replacement, check adjustment allowance, wear profile, orientation and fit with the impeller.
View the component guide →Volute Liner / Casing Liner
The volute collects slurry discharged by the impeller and withstands continuous erosion. Metal-lined, elastomer-lined and unlined casing designs are not interchangeable on appearance alone.
View the component guide →Frame Plate Liner Insert
Located at the rear or frame-plate side of the pump, this liner protects the pressure casing and forms part of the wet-end passage. Check the pump model, size code, bolt pattern, sealing faces and axial position relative to the impeller.
View the component guide →
Cover Plate Liner
The cover-side liner works with the throatbush and volute liner to protect the wet end. Segmentation, inserts and fastening arrangements vary by series, size and material configuration.
View the component guide →
Expeller & Expeller Ring
Used in centrifugal shaft-seal arrangements to reduce pressure at the packing or seal area.it does not define the geometry of a particular Warman model.
View the component guide →Check mechanical drive and seal parts separately. Pump shafts, sleeves, bearing assemblies, stuffing boxes, mechanical seals and drive connections must all be confirmed against installed dimensions and operating conditions.
Pump Shaft
The pump shaft transmits drive torque and locates the impeller axially. For an order, confirm the full pump model, shaft-end connection, thread or locking arrangement, bearing and seal seats, rotation and overall length.
View the component guide →
Shaft sleeve
The sleeve protects the shaft's sealing area and works with packing, a mechanical seal or an expeller seal.confirm the actual outside diameter, length, shoulders, keyways and surface condition from the installed part.
View the component guide →Bearing Assembly & Housing
The drive-end bearing assembly supports the shaft under radial and axial loads. Check the bearing designation, clearance, housing, end covers, lubrication and impeller axial-adjustment mechanism as a complete assembly.
View the component guide →Stuffing Box, Gland & Packing
The stuffing box, gland, packing and flush connections form a common shaft-seal arrangement. Check the pump model, shaft diameter, flush-water conditions, gland design, packing section and fit with the sleeve.
View the component guide →Mechanical Seal & Adaptor
Confirm the mechanical seal together with the rear liner, shaft sleeve and adaptor arrangement. Provide shaft diameter, seal-chamber dimensions, pressure, temperature, solids content, flushing plan and existing seal designation.
View the component guide →Coupling, Pulley & Drive Interface
Drive connections vary with direct or belt drive, speed and mounting base. For an enquiry, provide motor power, speed, shaft extension, center height, rotation, existing coupling or pulley details and guarding requirements.
View the component guide →No. At minimum, provide the complete pump model and size code, then verify rotation, liner material, impeller, shaft seal and serial or drawing. Different sizes and configurations within one series are not interchangeable by name alone.
Material names alone are insufficient. Confirm the casing construction, liner type, impeller and throatbush interfaces, axial dimensions and fastening method, then assess particle size, concentration, corrosiveness and temperature.
We do not publish numbers unsupported by a traceable OEM catalogue, drawing or installation record. Submit the nameplate, full model, serial number, drawing, used-part photographs or measured dimensions for further checking.
Provide the full pump model, size code, rotation, serial number, liner material, impeller and shaft-seal configuration, drawing, used-part photographs, operating conditions and target life. These support identification, material assessment, manufacturing coordination, quality control and finished-part delivery.
