ADCA PRESSURE OPERATED PUMP POP (4" x 4" – DN 100 x DN 100) DESCRIPTION The ADCAMat POP pressure operated pump is recommended in the transfer of steam condensate, oils and other non-hazardous liquids compatible with the construction, to a higher elevation or pressure. Under certain conditions, it can drain a closed vessel under vacuum or pressure. The pump can be operated using steam, compressed air or other gases, and is manufactured in carbon steel. OPERATION Liquid flows by gravity into the pump through an inlet check valve, lifting the float. At this point, the motive fluid intake valve is closed while the vent valve is open. As the float reaches its highest position the motive fluid intake valve opens and the vent valve closes, allowing the motive fluid to enter the pump body. The pressure in the pump builds up just enough to overcome backpressure. The pressurized liquid opens the outlet check valve and the discharge starts. The liquid discharged may be quantified through a special counter, enabling the pump to function as a reliable flow meter. When the float reaches its lower position the motive fluid intake valve closes and the vent valve opens allowing the liquid to fill the pump once again, repeating the cycle. MAIN FEATURES CE MARKING – GROUP 2 (PED – European Directive) Hardened stainless steel wear parts. High-endurance inconel springs. Low filling head to minimize installation space. No electric requirements or NPSH issues. Suitable for hazardous environments. Low running costs. Level gauge. Stroke counters.

FROM STEAM TRAPS 2. The operating medium (steam, compressed air or other gases) and its pressure. FILLING HEAD 3. The total lift or backpressure in bar the pump will have to overcome. This includes the change in fluid level elevation after the pump (0.0981 bar/m of lift), plus pressure in the return piping, plus the pressure drop caused by pipe friction and other system components. To accurately size a pressure operated pump, the following information must be provided: 4. Available filling head (see Fig. 1) in mm or any other dimension that allows its determination.

ADCA Table 4 FLOW RATE (kg/h) INSTALLATION WITH 600 mm FILLING HEAD ABOVE THE PUMP COVER MOTIVE PRESSURE (bar) Remark: Based on liquid specific gravity of 0,9 to 1,0. Example Condensate load Filling head Motive fluid Available pressure Vertical lift after pump Return piping pressure Piping friction pressure drop Calculations: Total back pressure: 1,2 bar + (10 m x 0,0981) = 2,181 bar. Assuming steam as motive medium at a pressure of 7 bar and a total backpressure of 3 bar, then according to Table 4 a DN 100 x 100 pump, with a capacity of 13740 kg/h, is the recommended size.
