Varkie S220 - 22kW - 29.5Hp - 3~ Horizontal Submersible Pump
Varkie S220 – Standard construction
Varkie S220X – Flameproof construction
Note:-The Varkie S220 supersedes the Varkie SVA220.
The Varkie S220 has been designed for transporting light slurries (up to an SG of 1.3) for applications where abnormal waste product needs to be removed.
Applications where these pumps have proved to be very successful are:
- Mining applications (including fiery mines),
- Industrial waste water,
- Agriculture irrigation,
- Construction site drainage,
- Large commercial and domestic water features.
This pump due to the vortex action has very good solids handling capabilities (up to 95 mm).
These units are designed to run horizontal. 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.
Careful consideration has been taken when designing this unit to minimise onsite 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 run in an oil bath. Onsite maintenance is not recommended but rather a standby unit as a backup.
The life of the mechanical seal has been extended by utilising an expeller in front of the mechanical seal, keeping debris away from the seal faces. Pressure relief slots have also been added 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 is lined with polyurethane 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 S220X 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.
