Service fee for wobble pump overhaul is $200.00 USD labor for most two cylinder air pumps. Pumps that require special size leathers run $40 USD extra for labor because we must produce the leather cup piston seal mold and seal from scratch. Additional parts and return shipping are extra.

 

Parts typically replaced are:

 

Piston leather cup seals

Check valve seals and parts if needed

Damaged cylinders and base if required 

Brass dowels and cotter pins

Bead blasting and epoxy painting of the base 

Brass polishing

Machining and silver soldering of damaged or missing parts if required

 

Piston cup leathers are always replaced on every overhaul. I have rebuilt many two and three cylinder vintage Morse, Siebe Gorman, Miller Dunn and John Date air pumps over the years. I have worked in the commercial diving industry for 20+ years and am a certified vintage diving equipment technician graduating from Diving Technologies Florida, USA. Most of my customers want air pumps overhauled so they can use them for helmet diving. All of my customers have reported complete satisfaction with my work.

If you decide to have your air pump serviced, please email us so that we know it's on the way. IMPORTANT: Please include a print-out of any email communication we have had regarding your pump rebuild. Include it with your shipment, then send it carefully packed and insured. Contact us at divingmachines@yahoo.ca for mailing address and phone number. We look forward to getting your treasures of the deep back in action.
