• Each Warman pump part has a unique name and a three-digit Basic Part Number.Parts with the same name have the same Basic Part Number, regardless of pump size.For example, the bearing assembly of every Warman pump has the Basic Part Number 005.
• Additional letters and numbers are added before and after the Basic Part Number to further define a component part of a particular pump,For example, Part Number E4110A05 identifies the impeller  to fit the casing of the 6/4E-AH pump, "A05" is the part material.

• Weir Warman pump parts mainly made of metal or rubber.
• Metal of high chrome white iron abrasion & corrosion resistant (A05 & A07 & A33 & A49 & A51 & A61) for impeller & liner, stainless steel (C21 & C23 & C26 & C55 ) for shaft sleeve & lantern ring or wet end parts,engineering steel (E02 & E62 & E05 & E65) for shaft and fasten bolts & nuts.
• Rubber of abrasion resistance natrual rubber R55 for impeller & wear liner,synthetic elastomers-Neoprene (S42) & Hypalon (S31) & EPDM (S01) & Nitrile (S10) & Polyurethane (U01 & U38 ) for impeller & liner & O ring & joint seals.
• Combinated material: J04 & J05 & J21 & J31 ceramic & chrome & tungsten carbide coated steel. 

• Generally a  Weir Warman slurry pump consist 30~40 units components and could be subdivided into the wet end,the mechanical end and the support end.
• The wet end clearly awared the slurry pass through parts,such as the impeller,volute liner,back liner and throatbush-the most wear parts of abrasion,corrosion and errosion.
• The mechanical portion of the pump includes the pump shaft, shaft sleeve, sealing arrangement, and the bearings assembly.
• The support end include the frame and casing plate.
• The wear parts include the wet end parts and some mechanical spares - shaft protection sleeve,shaft sleaing gland packing,lantern ring,lantern restrictor,expeller,expeller ring,stuffing box.

• As above talked,slurry pump wet end parts and some shaft sealing parts is the wear parts which need replace in regular time. 
• Managing and reducing the slurry pump wear is what AlphaFlo® does for our customers
• AlphaFlo® stock bulk regular slurry pump models wet ent parts for the shortest lead time to our customers.

The Weir Minerals Group Warman® brand slurry pumps with 60 years history are the world standard for heavy duty slurry pumping solutoins. AlphaFlo® horizontal and vertical slurry pump parts have been rigorously reverse engineered using  2D 3D modeling. First article inspection involves comparison to OEM parts followed by fit and material testing. All impellers have been performance tested to certify them against OEM Warman pump performance and equal service time.
