DHCL Group is a one-stop shop for all your pump needs. Many pump manufacturers provide "just a plain pump" for you to then accessorize and package into a complete product. And, certainly, we can do that for you too. But because we are not just a manufacturer, we can offer you much more. With 30+ years of experience in pump and pneumatic tools design, we specialize in collaborating with our customers to deliver a complete solution - a customized fully-accessorized pump (perhaps with digital control, customized housing, whatever's required) packaged, labeled, certified, and delivered to you ... ready to sell.
