Used EDWARDS QDP40 #83008 for sale

EDWARDS QDP40 is a diaphragm-style pump, designed to accurately and reliably move liquids using the application of pressure. It appeals to many users because of its compact, low-maintenance design, which is easy to install in confined spaces, and its adjustable flow rates. EDWARDS QDP 40 consists of a thermoplastic reinforced body, tough diaphragm and stainless steel valves, all housed in a lightweight PVC enclosure and protected by an IP 44 rating. An optimized design offers an efficient direct drive, and a two-stage gas ballast valve ensures prime against larger volumes and longer pipeline runs. QDP40 features a robust and easy-to-service drip-proof PTFE/capacitor motor with Thermal Cut-Out protection and a simple hand wheel to adjust the maximum allowable pressure at the pump outlet. QDP 40 is capable of handling a maximum continuous flow rate of 40 liters per minute, a maximum differential pressure of 0.8 bar, a maximum liquid temperature of 90°C, and a maximum shut-off pressure of 10 bar when using liquids with a viscosity up to 1000 cSt. It has a max suction-lift of up to 3 metres when using water. EDWARDS QDP40 also provides excellent protection against clogging of the internal components, thanks to its 316 SS strainer, non-return valve and check valves. EDWARDS QDP 40 is a long-lasting pump for applications such as pressurizing circuits, restoring pressure to systems, transferring liquids, refilling tanks or containers, and maintaining a constant pressure or flow in a system. Its lightweight, low-maintenance design makes it easy to install and service, making it a great solution for many applications where space is a concern.
