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)

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

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

LaBour was the FIRST (and still is the) Premier
Self Priming Pump Manufacturer.
