  1. LaBour - LPLA/LHLA Self Primer Pump

  2. LPLA/LHLA Design

  3. How it all started

  4. Hydrobalance

  5. LHLA/LPLA is Born + =

  6. Why change “the perfect pump” • Mechanical Seal development • Stricter shaft tolerances • Larger stuffing box • Ease of maintenance • Back Pull Out Design • Shaft stiffness (L3/d4) • Bearing design (7000 series duplex)

  7. OLD vs NEW STUFFING BOX DESIGN DHL/DPL LHLA/LPLA

  8. L3/d4(widely accepted is 60 max) d L

  9. Group S Comparison

  10. Discharge Arrangement LPLA LHLA H = Horizontal P = Perpendicular

  11. Models LHLA LPLA With Trap Less Trap

  12. Features & Benefits - LPLA/LHLA Liquid End Heavy Duty 316SS or higher Alloy Shaft Lip Seals Standard (Optional Lab. Seals) External Impeller adjustment using jack bolts AND shims Duplex Angular Thrust Bearing LaBour’s HYDRO-BALANCE guarantees suction lifts of up to 25 feet DPL/DHL ‘Wet End’ ANSI (LVA/TFA ) Back Pull Out Power End

  13. LHLA/LPLA Features • Considerably larger trap volume • Modular construction (you only replace what is worn). • Pump designed as a self primer (not an ANSI pump with trap) • Circular casing design (eliminating air pockets) • All pumps tested for 20” vacuum minimum

  14. Features & BenefitsStuffing Box Options (with or without Spiral Trac) Standard Bore Big Bore Taper Bore

  15. Self Priming Cycle 4. Air is expelled thru discharge. 5. Liquid re-enters casing/trap thru second throat to priming chamber. 6. Cycle continues until all air is evacuated from line. 3. Mixture of Air/Liquid is expelled into the separator. 2. Start pump, impeller pulls liquid from trap 1. Fill pump with initial priming charge.

  16. Competition • Gorman Rupp (industrial applications) • Flowserve (Durco) • Goulds • ANSI Mag (lined mag drive)

  17. Competition Comparison

  18. LHLA/LPLA Pump Applications • Vacuum Filtration (Komline Sanderson, Siemens, US Filter) • Sumps • Tank Car Unloading • Day Tank Transfer • Mine de-watering

  19. Tank Car Unloading

  26. Trouble Shooting Self Priming Pumps • No Initial Priming Charge • Wrong Direction of Rotation • Air leaks in the suction line • Discharge Check Valve without bleed line • Suction lift too high (high S.G. or friction loss) • Loss of Priming Charge • Low speed • Foaming liquid (does not release air well) • Packing type not designed for vacuum service • Wear or Corrosion

  27. LaBour was the FIRST (and still is the) Premier Self Priming Pump Manufacturer. Questions? Opportunities?
