Diaphragm pump DD-1

Valco Melton’s DD-1 Diaphragm Pump represents an innovative breakthrough in pump design. The electronic reversing control is extremely reliable and is not affected by normal wear characteristics of mechanical devices. The DD-1 Diaphragm Pump is automatically reversed by low-voltage, solid-state electronics. Many diaphragm pumps use air-powered mechanical devices, which reserve the pump stroke. These reversing mechanisms can “hang-up” and stall the pump when operated at low air pressure or when cycling at slow speeds. To overcome these limitations, common diaphragm pumps must be operated at air pressures high enough to ensure stroke reversal. For most applications, this results in an expensive waste of compressed air. In addition, mechanical reversing devices wear out, resulting in frequent downtime for maintenance and rebuilding. • The electronic reversing control offers extreme reliability • Not affected by normal wear characteristics of mechanical devices • Teflon diaphragms come standard • Can be cycled very slowly or operated at very low air pressure without stalling or hanging up • Lightweight, injection-molded nylon construction • Modular for fast, simple in-line service • No lubrication required
