• 4, 5, & 6 Vane Enclosed Impellers:
• 4 Vane Enclosed Impeller – For coarser particle slurry handling (Basic Code. 145). 5 Vane Enclosed Impeller – Standard for heavy-duty slurry applications (Basic Code 147).6 Vane Enclosed Impeller – For higher efficiency slurry pumping (Basic Code 058)
• 4, 5, & 6 Vane Differential Impellers:
• For effective dry shaft sealing in high suction head slurry duties (HE1,HE2)
• 4, 5, & 6 Vane Semi Open Impellers:
• For larger particle clearances and wood tramp handling capabilities in slurries ( 051,052,053,056)

• "TL1" means "Thick Liner". often in a slurry pump wet end parts,such as the volute liner,frame plate liner insert,throatbush.The "TL1" parts could replace the standard parts  directly without change other pump parts configuration.
• For example Warman AH pump 20/18 TU-AH.
• Volute Liner U18110TL1A05
• (Standard U18110A05)
• Throatbush U18083TL1MA05 ( Standard U18083MA05)
• Frame Plate Liner Insert-FPL Insert.U18041TL1MA05 (Standard U18041MA05)

• "HS1" means "HI-SEAL". It's a update of standard "Packing Gland" and "Centrifugal Seal" with less liquid leakage and lower pump consumption power. They are often in a slurry pump "Shaft Seal" parts and connected relation parts "Frame Plate " and "Frame Plate Liner Insert".
• For example Warman AH pump 8/6 E-AH 
• Hi-Seal Centrifugal Seal.
• Expeller EAM028HS1A05 (Standard  EAM028A05)
• Expeller Ring EAM029HS1A05 (STD.EAM029A05)
• Lantern Ring E063HS1C23 (STD.E063C23)
• F.P.L. Insert F6041HS1A05 (STD.F6041MA05)
• Frame Plate EAM6032PRD21 ( STD.EAM6032D210

• "MS1" means "Mechanical Seal", often in pump "frame plate liner insert" or "frame plate liner" for rubber liner pump.
• For example Warman AH pump 10/8F-AH
• Metal Lined Pump with Mechanical Seal
• F.P.L.Insert G8041MS1MA05 (STD.G8041MA05)
• Rubber Lined Pump with Mechanical Seal
• Frame Plate Liner G8036MS1MR55 (STD.G8036MR55)

WRT means "Wear Reduction Technology" -  a superior upgrade for  existing Warman AH pump designed to enhance efficiency and improve wear performance.

• Increased wear life – the impeller throatbush combination will increase wear life between 30% and 50%
• Power savings – lower pump power 
• Cost reduction – higher pump efficiency sustained over a longer pumping operation time
• Retrofit – new design parts retrofit to your current Warman pump
• Lower NPSH requirements – results in enhanced hydraulic performance and extended wear life
• Material combinations – rubber or metal part combinations available

• 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, E-4-110-A05  "E"means pump frame type. "4" menas pump discharge size 4 inch."110" is a basic part numer,"A05" is the part material.

• 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.

• 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. 

• 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 AH 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.
