1 WARMAN Series A, Type T AH, HH, and L Slurry y Pumps

2 Warman Series A Pum Cartridge-type Shaft and Bearing Assembly A large diameter shaft with a short overhang minimizes deflection and vibration. Heavy-duty, grease-lubricated cylindrical and/or taper roller bearings are enclosed in a cartridge-type housing protected at both ends by a rotating labyrinth with double piston ring and patented -10 grease purged lip seal (see Figure 1 on page 6). Only four through bolts are required to hold the cartridge assembly in the frame. Pump Frame A rigid, one-piece casting cradles the cartridge shaft and bearing assembly. A minimal number of through bolts hold the pump casing to the frame. An easy means of external impeller adjustment is provided in a convenient position below the bearing housing. Slip-Fit Shaft Sleeve A reversible, 420 stainless steel shaft sleeve, through hardened to Rockwell 55C, with 0-rings at both ends, completely protects the shaft. Interchangeable Shaft Seal Warman pumps provide complete interchangeability of seal arrangements. Full-flush, low-flow centrifugal, or mechanical seals can be fitted to any size pump. 2 Centrifugal Shaft Seal Warman s centrifugal seal eliminates the need for a gland-water system and potential slurry contamination. More than 70% of all Warman pumps are equipped with this seal arrangement.

3 ps: Design Features Impeller Front and rear shrouds have pump-out vanes. This design reduces recirculation and seal contamination. Hard metal and molded elastomer impellers are interchangeable. Cast-in impeller threads require no impeller insert or nuts. EASE OF MAINTENANCE FEATURES: Through-Bolt Design Minimum Number of Casing Bolts Zinc Chromate and Stainless Steel Nuts and Bolts Slip-Fit Shaft Sleeve Cartridge-Type Shaft and Bearing Assembly Cast-In Impeller Threads Impeller-Release Collar on Large Models Liners Positively Attached Outer Casing Casing halves of cast or ductile iron with external reinforcing ribs contain the wear liners and provide high operating pressure capabilities. Positively Attached Liner Hard metal liners are interchangeable with pressure molded elastomers. The elastomer liners are bolted, not bonded, to the outer casing. Elastomer seal rings back all liner joints. 3

4 Impeller Designs A leader in manufacturing heavy-duty slurry pumps Warman s leadership in slurry pump design and performance assures you the highest possible return on your investment. Throughout the world, Warman pumps have established records for minimal maintenance. A wide selection of sizes, with several liner and impeller materials, permits Warman pumps to be tailored to meet your specific requirements. This means maximum pump efficiency and productivity for your particular application. Warman s investment in slurry pump development is your assurance of continued efficiency, dependability and profitability. ➊ ➋ ➊ 4, 5, & 6 Vane Enclosed Impellers 4 Vane Enclosed Impeller For coarser particle slurry handling 5 Vane Enclosed Impeller Standard for heavy-duty slurry applications 6 Vane Enclosed Impeller For higher efficiency slurry pumping ➌ ➍ ➋ 4, 5, & 6 Vane Differential Impellers For effective dry shaft sealing in high suction head slurry duties ➌ and ➍ 4, 5, & 6 Vane Semi Open Impellers For larger particle clearances and wood tramp handling capabilities in slurries 4

5 Typical Applications Erosion and Chemical Resistant Polymers All wear materials are produced in Warman s own rubber shop and foundries worldwide. Various grades of natural rubbers, synthetic elastomers, and polyurethanes have been developed to yield optimum service lives in Warman pumps for a wide range of applications. The operating range for polymeric materials is being expanded by continuous research and development programs.

7 l Cro s s - S e c t i o n VARIATIONS OF THE WARMAN CENTRIFUGAL SHAFT SEAL AVAILABLE WITH STANDARD OR OPTIONAL HS (HIGH-SEAL) CENTRIFUGAL SEALS METAL LINED The expeller ring is interchangeable with a gland sealed stuffing box. The expeller and expeller rings are made of 650 BHN high chrome iron as a standard but can be provided in other materials suitable for specific applications. ELASTOMER LINED RULE OF THUMB: If the suction pressure of the pump is no greater than 10% of the discharge pressure, the application is suitable for a centrifugal shaft seal. For variations from this general rule, consult your Warman Representative. UNIQUE WARMAN IMPELLER DESIGN CONVENTIONAL DESIGN Outward spiral of slurry in conventional pumps causes serious recirculation and consequent wear at the close impeller clearances. The pump-out vanes and concave impeller vane of a Warman pump force the slurry to form a double inward spiral. This results in uniform wear, a greater utilization of wearing parts, an increased shaft seal life, and sustained high efficiency. WARMAN DESIGN 7
