Varkie S55 Horizontal Submersible Pump - 5.5kW - 7.4Hp - 3~
The Varkie S55 supersedes the Varkie SVA55. It has a horizontal submersible configuration for applications where an abnormal waste product needs moving.
Varkie S55 – Standard construction
Varkie S55X – Flameproof construction
Note:-The Varkie S55 supersedes the Varkie SVA55.
The Varkie S55 is for use in transporting light slurries (up to an SG of 1.3) for applications where an abnormal waste product needs moving.
Applications where these pumps are proven to be very successful in:
- Mining applications (including fiery mines),
- Industrial wastewater,
- Agriculture irrigation,
- Construction site drainage,
- Large commercial and domestic water features.
Varkie S55 Solids Handling Pump
This pump due to the vortex action has very good solids handling capabilities (up to 70 mm).
These units design are to run horizontally. This allows the unit’s motor to stay partially submerged, when the pump loses prime and stops pumping, allowing the product to still cool the motor.
This model has a four-pole motor, reducing the speed and extending the wear life of the pump components.
The wet end consists of a single full vortex impeller with a volute casing and requires no adjustment.
Working Life Improvements
Careful consideration is taken in the design of this unit to minimise on-site maintenance by utilising sealed for life bearings, simple motor seal and a mechanical seal with a rubber bellow, protecting the seal spring from the product, which runs in an oil bath. On-site maintenance is not a recommendation, but rather a standby unit as a backup.
The extension of the mechanical seal life is achieved by utilising an expeller in front of the mechanical seal, keeping debris away from the seal faces. Pressure relief slots is an addition to the oil box to reduce the pressure on the seal. This allows the product to splash, from the expeller, through these slots onto the motor and provide a bit of extra cooling when the product level is low.
The wear plate behind the impeller has a polyurethane lining to improve the wear life.
This unit comes standard on a skid base for easy transportation in mines.
The unit can be mounted on an Amandla Float when required.
The Varkie S55X is Ex d I approved, according to SANS 60079-1 for underground use in fiery mines. All international 3-phase standard voltage ratings are available from 380 to 1000V.
Material construction ranges from standard cast iron/chrome iron and stainless steel constructions or a combination thereof. Other special materials of construction are available on request.
