One of the nice things about doing business with HMC is the consistency we offer in our product line. While our competitors rush out new products, we fully test in house and have a group of close customers who demo new items for quality and ease of use. In the last two years, one of HMC's competitors in the gas caddy market has offered 3 different models of pumps. At first they had a standard 2 vane pump that felt like sand paper when you rotated it. After publishing testimonials from customers about how much better it was over the traditional aluminum cast pump, they then moved to offering a three vane pump. Well, it appears they have given up on both their standard and professional and now offer yet another pump. Meanwhile, HMC has been building their Aluminum Cast, 3 Vane PPS pump for over 3 years now....and it's the a similar design as was built under Marshalltown Pump, Western Mfg. Pump, and Handy Industries LLC Pump....the design has been proven since the early 70's....that's a pretty good testament. We buy our castings locally and machine them in house. The vanes and rotors come from an American company in Mississippi and are also machined in house. Finally we assemble the pump complete in house...keeping a close eye on tolerances and quality construction. The best thing about consistency is that when you need that pump rebuilt, we can do it, because we are still building them new today.
