VIKING GP-414 BOOSTER PUMPS
VS. PROGRESSING CAVITY PUMPS:
Significant Space Savings – the pump assembly is approximately 12.7cm in length. A progressing cavity pump offering similar performance will be 38cm or more in length, often requiring a special door if LACT is mounted in an enclosure.
Motor Speed Operation vs. requirement for slower RPMs, requiring gearbox which adds system cost, footprint, maintenance (lubrication) and two shaft alignments – motor to gearbox and gearbox to pump.
More Forgiving of Operator Error, especially run dry. Progressing cavity pumps have zero run dry capability. Running dry results in catastrophic failure resulting in expensive replacement of rotor and or stator.
Less Space Required for Maintenance work. Almost double the length of the pump assembly is required to replace the stator of a PC pump.
VS. OTHER EXTERNAL GEAR PUMPS:
Single Mechanical Seal versus two mechanical seals. Mechanical seals are the most common cause of failure in a gear pump, and using two seals doubles the chances of unplanned downtime.
Three Pump Sections (2 static seals) vs. seven (6 static seals). Fewer static seals for less potential leak paths and chances of runout.
Fluid-lubricated Sleeve Bearings means no re-greasing or maintenance vs. competitor roller bearings that require re-greasing every six months.
VS. PLUNGER PUMPS:
Significant Space Savings, easily mounted in an enclosure.
Motor Speed Rotary Pump vs. triplex reciprocating piston pump with gearbox and crankshaft to keep lubricated, and check valves, seats and seals to replace.
Smooth Flow vs. high pulsation flow that is hard on surrounding equipment.
Less Auxiliary Equipment. Motor speed pump, so no gearbox required. Smooth flow, so no pulsation dampeners required.
