A52S Mini Max Full Conversion Kit | Transform Your Keene A52S into a Mini Max Power Sluice or Highbanker

One Sluice. Multiple Mining Systems. Unlimited Possibilities.

The Keene A52S Mini Max Full Conversion Kit transforms your Keene A52S Super Sluice into a versatile Mini Max Power Sluice, battery-powered recirculating concentrator, or portable highbanker in just minutes. Designed by Keene Engineering, this complete conversion package gives prospectors the flexibility to operate virtually anywhere—from remote streams with limited water flow to recirculating systems at camp or even in your garage.

With the addition of a 12-volt pump system, you can process concentrates quietly using recirculated water, making this setup ideal for cleanup work, sampling, or prospecting in locations where flowing water isn't available. When you're ready, simply convert the system back into a traditional A52S sluice, highbanker, or dredge configuration in just a few minutes.

Why Choose the Mini Max Conversion Kit?

The Keene A52S is already recognized as one of the finest gold recovery sluices available. The Mini Max Full Conversion Kit expands its capabilities by allowing you to use the same sluice in environments where traditional stream flow isn't available.

Run quietly from a battery-powered pump, process concentrates at home, or convert the system into a portable highbanker for remote locations. Instead of purchasing multiple recovery systems, this kit lets one piece of equipment perform several different jobs.

Keene A52S Mini Max Full Conversion Kit with Pump

Get more use from your Keene A52S sluice box by converting it into a powered highbanker or Mini Max-style recirculating recovery system. The A52S Mini Max Full Conversion Kit includes the hopper, classification components, pump, hose, valve, and fittings needed to expand the capabilities of an existing A52S.

This versatile conversion is ideal for low-water conditions, remote locations, and recirculating operation at home or camp. The conversion components can be installed or removed in minutes, allowing the A52S to return to its original stream-sluice configuration when desired.

Expand the Capabilities of Your A52S

The standard Keene A52S is an effective stream sluice. Adding this full conversion kit allows it to operate with a controlled 12-volt water supply, providing more setup options when natural stream flow is limited or unavailable.

Depending on the configuration, your A52S can be used as:

  • A powered highbanker

  • A Mini Max-style power sluice

  • A recirculating concentrate-processing system

  • A standard stream sluice after removing the conversion components

Important Compatibility Notice

This is a conversion kit for an existing Keene A52S sluice box. The A52S sluice itself is not included.

This kit is specifically identified by Keene as part number A52SMMKIT1. Confirm that you own the compatible A52S model before ordering.

Additional Equipment Required

Depending on the intended setup, you will also need:

  • Keene A52S sluice box

  • Suitable 12-volt battery or power source

  • Water reservoir for recirculating operation

  • Tailings container or settling system

  • Appropriate battery cables and connections

  • Classification and cleanup tools

These items are not included unless specifically listed as part of the kit.

Recirculating Operation

For home, camp, or low-water operation, place the pump inside a suitable reservoir and position the discharge end of the A52S over a tailings container or settling area. Arrange the system so discharged sediment settles before water returns to the pump.

Use the included ball valve to adjust water flow. Begin with moderate flow and make small adjustments until lighter material clears the recovery section while heavier material remains concentrated.

Setup Tips

  • Assemble the hopper and end-cap components according to Keene’s instructions.

  • Position the A52S securely with a consistent downward slope.

  • Connect the hose, pump, and ball valve before supplying power.

  • Never operate the pump dry.

  • Classify material to a consistent size before processing.

  • Feed material gradually to avoid overwhelming the recovery system.

  • Disconnect the battery before adjusting or servicing the pump.

Ideal For

  • Existing Keene A52S owners

  • Low-water prospecting locations

  • Creek-bank highbanking

  • Paydirt and concentrate processing

  • Home and camp recirculating systems

  • Prospectors who want several operating configurations from one sluice

The World Famous Keene A52S does it all. Not only is it the best sluice box on the market today, it now converts into a Mini Max Style Sluice box system utilizing a 12-volt pump system.
