Varkie S75 Horizontal Submersible Pump - 7.5kW - 10.1Hp - 3~
The Varkie S75 Solids Pump supersedes the Varkie SVA75. It has a horizontal submersible pump configuration for applications where abnormal waste product needs to be removed.
Varkie S75 – Standard construction
Varkie S75X – Flameproof construction
Note:-The Varkie S75 supersedes the Varkie SVA75.
The Varkie S75 usage 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 proven to be very successful, are:
- Mining applications (including fiery mines),
- Industrial wastewater,
- Agriculture irrigation,
- Construction site drainage,
- Large commercial and domestic water features.
Varkie S75 Solids Handling Pump
This pump due to the vortex action has very good solids handling capabilities (up to 70 mm).
These units are designed 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.
Careful consideration is given 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.
Working Life Improvements
The extension of the mechanical seal life, by using 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 has a 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 S75X 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.
