Product Description
Wilden P1 Clamped Plastic Pump for Chemical Transfer
The Wilden P1 Clamped Plastic Pump is a compact 13 mm (½-inch) air-operated double-diaphragm pump for chemical transfer and rugged industrial duties. Its polypropylene or PVDF wetted housing provides corrosion resistance for many compatible process liquids.
Moreover, clamp-band construction gives technicians quick access to the internal components. Consequently, the pump combines dependable operation with simple installation and efficient maintenance.
Wilden P1 Pump Flow and Pressure
Maximum flow depends on the selected diaphragm:
- Rubber: Up to 56 lpm
- TPE: Up to 56.8 lpm
- PTFE: Up to 53.4 lpm
In addition, maximum discharge pressure reaches 8.6 bar or 125 psi. However, actual output depends on compressed-air volume, viscosity, discharge pressure and piping resistance.
Therefore, users should select the P1 AODD pump from its performance curve rather than relying only on the maximum flow figure.
Key Features of the P1 AODD Pump
- 13 mm or ½-inch liquid inlet and discharge
- ¼-inch FNPT compressed-air inlet
- Maximum flow up to 56.8 lpm
- Maximum pressure of 8.6 bar
- Solids passage up to 1.6 mm
- NPT or BSPT threaded connections
- Polypropylene or PVDF wetted housings
- Rotatable inlet and discharge
- Rubber, TPE and PTFE diaphragm options
- Clamp bands for faster servicing
- Strong wet and dry suction lift
- Lube-free pneumatic operation
- Simple installation and maintenance
Together, these features make the Wilden P1 Clamped Plastic Pump suitable for compact transfer, circulation, sampling and container-unloading systems.
Pro-Flo Clamped Plastic Pump Design
The Pro-Flo clamped plastic pump uses clamp bands to secure the manifolds, liquid chambers and centre section. Consequently, technicians can dismantle and reassemble the pump with a single tool.
Moreover, rapid access to the diaphragms, valve balls and seats can reduce servicing time. Therefore, the Wilden P1 pump suits facilities that require regular inspection, cleaning or component replacement.
Polypropylene and PVDF P1 Construction
The Wilden P1 Clamped Plastic Pump is available with polypropylene or PVDF wetted housings.
Polypropylene suits many compatible acids, alkalis and treatment chemicals. Alternatively, PVDF provides different chemical and temperature resistance for selected aggressive liquids.
However, neither material is compatible with every fluid. Therefore, users must verify the chemical concentration, temperature and complete liquid composition before ordering.
P1 Diaphragm and Elastomer Options
The P1 plastic diaphragm pump supports rubber, TPE and PTFE diaphragm configurations.
Moreover, available elastomers include Buna-N, EPDM, FKM, Neoprene, PTFE, polyurethane, Saniflex and Wil-Flex. Each material provides different chemical, temperature and abrasion resistance.
Consequently, the diaphragms, valve balls, valve seats and seals should all match the transferred liquid.
Threaded P1 Chemical Pump Connections
The Wilden P1 pump uses ½-inch NPT or BSPT threaded inlet and discharge connections. Moreover, both connections are rotatable.
Therefore, installers can adjust the inlet and discharge positions to match compact pipework, hoses or equipment skids. However, users should confirm the required thread standard and sealing material before installation.
P1 Solids Handling and Suction Performance
The Pro-Flo P1 pump passes compatible solids up to 1.6 mm or 1/16 inch. As a result, it may handle clean liquids and fluids containing limited small particles.
Maximum dry suction lift reaches:
- Rubber: Up to 6.1 m
- TPE: Up to 5.8 m
- PTFE: Up to 5.18 m
Meanwhile, wet suction lift reaches 9.5 m with rubber and 9.8 m with TPE or PTFE. However, viscosity, elevation and inlet restrictions affect actual performance.
Wilden P1 Clamped Plastic Pump Applications
The Wilden P1 Clamped Plastic Pump may support:
- Chemical sampling and transfer
- Acid and alkaline handling
- Water-treatment chemicals
- Drum and container unloading
- Cleaning-chemical transfer
- Ink and coating circulation
- Small filtration systems
- Laboratory and pilot equipment
- Equipment skids
- Corrosive wastewater transfer
- Industrial dosing-system circulation
- General low-flow processes
For example, polypropylene may suit compatible general chemicals. Alternatively, PVDF may support selected aggressive liquids after a complete compatibility review.
Moreover, operators can regulate the transfer rate by adjusting the compressed-air supply.
Selecting a Wilden P1 Chemical Pump
Correct selection depends on flow, pressure, chemical concentration, temperature, viscosity and particle content.
In addition, users should confirm the housing, diaphragm materials, thread standard, suction conditions and available compressed-air volume. Therefore, the Wilden P1 Clamped Plastic Pump should be configured around the complete hydraulic and chemical duty.
Otherwise, incompatible materials may cause premature wear. Similarly, insufficient air volume may reduce flow and efficiency.
Why Choose the Wilden Pro-Flo P1?
The Pro-Flo P1 combines corrosion-resistant thermoplastic construction with quick clamp-band servicing. Moreover, its rotatable connections, dependable suction and broad elastomer selection support varied low-flow industrial applications.
Consequently, this half-inch AODD pump provides a practical solution for UAE facilities requiring reliable chemical transfer and simplified maintenance.
