Goldfinch Multistage Vertical Pumps
Goldfinch column pumps are semi-submersible centrifugal sump pumps that are designed for pumping different media such as gas condensate, oil, oil products, fire hazardous liquids, water with oil or solid impurities and others. KVP pump series could be installed into underground tanks or other configuration tanks Improved design and high quality components makes them virtually free of service and low cost ownership.

o Custom dimensions
- Shaft sealing options
o API 610 compliant cartridge designs
- Single mechanical seal, including dry running types
- Unpressurized and pressurized double mechanical seal
- Custom dimensions
- Closed multivane impeller with front and back rear rings
- Open multivane impeller with back vanes
- Suction strainer
- API Standard Seal Flush Plan 13 for primary seal. Buffer liquid in chamber between primary and secondary seals with volume enough for cooling and lubricating secondary seal for long operation without changing.
- Multiple API seal flushing, buffer liquid and quench system piping plans
- Instrumentation for leakage detection for both primary and secondary seals. External Reservoir and piping plans for buffer liquid not required.
- Bearing cooling (API Plan A) Not Required. Drive shafting double shielded bearings are selected with required operation temperature.
- Internal or external bearing flushing Not Required. Drive shafting with double shielded bearings greased for life eliminates
- Internal or external bearing flushing system, reduce pump operation cost.
- Pump Casing and Cover features metal to metal fit with fully confined, controlled compression gasket to endure proper sealing and alignment.
- Suction Pipe
- Dynamically Balanced Precision Cast Impeller minimizing vibrations and guarantees smooth operation over a range of flows.
- Modular construction with a wide range of housings and impellers allows the hydraulics to be matched to the service requirements.
- Thrust Pot with API 40° angular contact bearings in back-to-back arrangement enables standard electrical motors to be used and fulfills API 610 bearing life criteria.
- Standard Reverse Vane Impeller offers repeatable performance throughout the life of the pump. Open impellers available for stringy or fibrous liquids
- Large Basket Strainer resists corrosion, different materials available.
- Factory Flanged Discharge system available in a variety of configurations and enhance installation process.
- API 682 Seal Chambers allow for installation of single or dual unpressurized mechanical seals to meet required safety and environmental requirements.
- A Gas Mechanical Seal provides the lowest fugitive emissions without complex piping, instrumentation or regulation. A complete instrumentation package is available to control the flow of buffer gas to the seal chamber and monitor critical operating parameters.
- The Diffuser Casing Design balances the radial thrust. Regardless of the number of stages used, or the head developed by the pump, the radial load carried by the sleeve bearings is minimal.
- Inducer can be added to reduce NPSHR to minimize tank inventory.
- Front and Rear Repelling Vanes replace erosion-prone wear rings.

- Custom designs available for limits exceeding those that listed
- Custom Engineered Slurry Hydraulics ensures safe, reliable and efficient performance.
- High Chrome Iron Wet End resists abrasion. Increased wall thickness on the wearing parts offers longevity.
- The Impeller is keyed to the pump shaft and secured using an impeller nut.
- Repelling vanes reduce wear and recirculation.
- Shafts are designed to operate approximately 30% below the first critical speed.
