DP 30 METAL & PLASTIC PUMPS
The DP30 Metallic and Plastic Pump User Manual provides detailed instructions for the operation, installation, and maintenance of DP30 diaphragm pumps, available in both metallic and plastic versions.
- Metallic Pump: Operates at pressures from 0 to 8.4 bars, with a temperature range of -18°C to 100°C. It has a maximum capacity of 894 lpm and can handle solid particles up to 8 mm.
- Plastic Pump: Operates at pressures from 0 to 7 bars, with the same temperature range and capacity as the metallic pump, also handling particles up to 8 mm.
The manual details materials such as aluminum, stainless steel, and polypropylene for various parts. Diaphragm materials include Neoprene, Buna-N, EPDM, PTFE, Viton, Santoprene, and Polypropylene, each with specific temperature and chemical resistance properties.
The pump uses two diaphragm chambers connected by a rod, moving in a reciprocating action for suction and discharge. An automatic air distribution valve ensures continuous fluid movement.
Installation involves proper hose connections, using manometers and valves for pressure monitoring, and regulating air supply. Precautions include minimizing suction line length and using flexible hoses to reduce vibration.
Diaphragm pumps are versatile for fluid transfer from tanks, as submerged or barrel pumps, effective up to 6 meters depth with proper cavitation management.
Air pressure should not exceed 7 bars. Regular lubrication of air distribution and pilot valves is necessary. Proper support for air supply lines is crucial to prevent damage.
The manual provides solutions for common issues like pump failure, insufficient capacity, and excessive vibration. It emphasizes adhering to air pressure limits and proper air connection sizes.
The pump can operate without lubrication, but poor air quality may require it. An airline lubricator should deliver one drop of SAE 10 oil per 10 liters/sec of air. An air dryer can prevent freezing from water in compressed air.
Initially, open the air supply valve partially. Adjust the valve for optimal air flow if cavitation occurs.
Flush the pump after each use to prevent damage from settled particles. Drain completely in freezing conditions.
Common issues include pump failure, no fluid transfer, and fluctuating flow. Solutions involve checking and cleaning components like air valves and O-rings.
Ensure all connections are tight, use a conditioner, and avoid over-tightening capscrews. Ground the pump to prevent static sparking and wear protective gear during maintenance.
If a diaphragm fails, hazardous fumes may enter the air end. Safely dispose of exhaust air, and submerge the pump only if compatible with the liquid.
Includes steps for maintaining air valve, pilot valve, and diaphragms, such as disassembly, inspection, cleaning, and reassembly, ensuring proper lubrication and alignment.
Comprehensive lists for air valve and pilot valve repair kits, detailing each component and quantity.
Install the second bumper over the diaphragm rod, align capscrew holes, and attach outer casing and manifolds using capscrews, nuts, and washers.
Includes main body, oil seal, diaphragm rod, gaskets, and capscrews for assembly and maintenance.
Uses double diaphragms with a Teflon diaphragm supported by a rubber diaphragm for extended service life.
Disconnect air supply, inspect installation, remove air inlet cap, check actuator pins for wear, replace O-rings, and lubricate before reassembly.
Shut off lines, disconnect air supply, discharge fluid, inspect check balls and valve seats, replace worn parts, and ensure proper seating for optimal operation.
Always switch off air supply and release pump pressure before maintenance to avoid accidents.

DP30 METALLIC and PLASTIC PUMP USER MANUEL PRINCIPLE OF PUMP OPERATION The diaphragm pump is consisted of two diaphragm chambers and two diaphragms. The diaphragms are connected to each other with a diaphragm rod and move in a reciprocating action. As one diaphragm performs the discharge stroke, the other diaphragm which is connected with the rod is pulled to perform the suction. At the end of the stroke, an air distribution valve automatically shifts, reversing the entire sequence, filling and pumping from alternate chambers. Mutual movements that repeated continuously ensure suction and discharge...

DP30 METALLIC and PLASTIC PUMP USER MANUEL INSTALLATION & START-UP The interconnections of the diaphragm pump are straightforward. The fluid is taken from the bottom manifold and discharged at the upper manifold. Diaphragm pumps are characterized by turbulence flow. To prevent turbulence flow, the flexible hoses are installed upstream the suction and the discharge port. In order to observe the pressures at the suction and discharge parts of the pump and adjust the flow rate, the manometers and valves are attached at the suction and discharge ports. When one or both valves are closed down, the...

DP30 METALLIC and PLASTIC PUMP USER MANUEL AREAS OF APPLICATION Diaphragm pumps can also be used as submerged pump. It is necessary to maintain the exhaust port of the pump above the liquid surface with pipe or hose. Diaphragm pumps can be used to transfer the fluid in the tank readily by connecting them to the bottom of the tank.
Open the catalog to page 18
DP30 METALLIC and PLASTIC PUMP USER MANUEL Diaphragm pumps can also be used as barrel pumps. They have effective suctions ability and able to transfer all the fluid in the barrel The diaphragm pumps are able to transfer fluids at 6 meter of deepness. Cavitation might obstruct the operation. To prevent this, the air in the hose between the pump and fluid should be discharged.
