Used EDWARDS STP-301 #293649225 for sale

EDWARDS STP-301 is a hydraulically-driven duplex submersible pump designed to transfer clean, non-corrosive liquid consisting of water, fuel oils, diesel, lubricating oil, and various other petroleum products. This pump consists of two hydraulic pumps connected together into a single unit, allowing a single motor to power both pumps. The motor is powered by either an electric or a diesel motor. An internal casing, made from cast iron, covers the two rotary cylinders, creating a hollow space between the two pumps. The rotary cylinders are connected to an inner shaft that is driven by the motor. The fluid enters through intake ports located in the bottom of the pumps, along with small amounts of air, and is drawn up and collected in the main cylinder. As it is pumped through the cylinders, oil is trapped and contained within the center of the cylinders, providing oil pressure and lubrication for the pump's components. The fluid is then forced out of the pump through the delivery ports located on the side of the pump, which are designed to deliver a maximum of 62.4 m3 of fluid per hour. The pressure and speed at which the fluid is pumped can be adjusted via the pressure regulating and speed control valves located on the top of the pump. These valves allow the operator to fine-tune the pressure and speed of the pump to meet the needs of their applications. STP-301 is also equipped with an anti-siphon valve to prevent the contents of the pump from flowing back up into the intake. This valve is located at the bottom and acts as a check valve to prevent the contents from flowing in the opposite direction. This pump is designed for use in hazardous environments such as chemical plants, and is certified for use in Class I, Division 1, Groups D and E hazardous locations. EDWARDS STP-301 pump's design offers advancement in terms of precision control and low maintenance costs. Its rugged construction ensures longevity in the harshest of environments, while a 480 V motor ensures reliable operation. STP-301 is the perfect choice for applications where dependable, efficient pumping performance is a must.
