Product Description
Wilden PS420 Bolted Metal Pump
The Wilden PS420 Bolted Metal Pump is a 38 mm (1½-inch) air-operated double-diaphragm pump designed for demanding industrial fluid-transfer applications.
Its enhanced FIT wetted path supports improved flow, while the bolted construction provides dependable product containment. Moreover, the Pro-Flo SHIFT air distribution system helps reduce unnecessary compressed-air consumption during operation.
PS420 AODD Pump Flow Performance
Maximum published flow depends on diaphragm selection:
- EZ-Install TPE: Up to 510 lpm
- Rubber: Up to 500 lpm
- Full-Stroke PTFE: Up to 485 lpm
Maximum discharge pressure reaches 8.6 bar or 125 psi. Therefore, users should select the diaphragm according to chemical compatibility, temperature, suction requirements and required output.
Key Features of the Wilden FIT Pump
- 38 mm or 1½-inch liquid connections
- 3/4-inch FNPT compressed-air inlet
- Maximum flow up to 510 lpm
- Maximum pressure of 8.6 bar
- Solids passage up to 6.4 mm
- NPT or BSPT threaded connections
- Pro-Flo SHIFT air distribution system
- Secure bolted metal construction
- Aluminium, ductile-iron and stainless-steel options
- Rubber, TPE and PTFE diaphragm choices
- Portable and submersible capability
- High suction-lift performance
- Matching footprint for compatible clamped pumps
Together, these features make the Wilden PS420 Bolted Metal Pump suitable for transfer, circulation, unloading and solids-containing fluid duties.
FIT Bolted Metal Pump Construction
The FIT design uses bolted liquid chambers and manifolds to support reliable containment. Therefore, it provides a robust solution for applications where leakage prevention and repeatable assembly are important.
Wilden designed the pump with the same bolt-down footprint and inlet and discharge positions as compatible Wilden clamped pumps. Consequently, facilities can replace an existing clamped model without extensive changes to piping or foundations.
Available metal-body options include aluminium, ductile iron and stainless steel. Therefore, engineers can select the construction according to corrosion resistance, abrasion and liquid compatibility.
Pro-Flo SHIFT Air System
The Wilden PS420 Bolted Metal Pump includes the Pro-Flo SHIFT air distribution system.
As each diaphragm stroke approaches completion, the system regulates the compressed air entering the chamber. Consequently, it limits unnecessary chamber overfilling while maintaining the required pumping action.
Moreover, the optimised air system provides more liquid flow per unit of compressed air. As a result, facilities may reduce air consumption, electrical demand and operating costs.
PS420 Threaded Pump Connections
The PS420 uses 1½-inch NPT or BSPT threaded inlet and discharge connections. Therefore, it suits installations requiring threaded process piping.
In contrast, the related PS430 uses DIN or ANSI flanged connections. Consequently, users should confirm the required connection standard before ordering.
Diaphragm and Displacement Options
Rubber, EZ-Install TPE and Full-Stroke PTFE configurations each provide approximately 1.1 litres of displacement per stroke.
However, diaphragm material affects flow, chemical compatibility, suction lift and service life. Therefore, users should consider both the liquid properties and the hydraulic requirement when configuring the Wilden PS420 Bolted Metal Pump.
Solids Handling and Suction Lift
The pump can pass solids up to 6.4 mm or ¼ inch in diameter. Consequently, it may transfer suitable fluids containing suspended particles.
Published dry suction lift includes:
- Rubber: Up to 5.9 m
- EZ-Install TPE: Up to 6.2 m
- Full-Stroke PTFE: Up to 5.5 m
Wet suction lift reaches 9.0 metres with rubber or TPE and 9.3 metres with PTFE. However, actual suction performance depends on viscosity, pipe losses, air supply and installation conditions.
Wilden PS420 Pump Applications
The Wilden PS420 Bolted Metal Pump may support:
- Chemical transfer
- Paints and coatings
- Resin and solvent handling
- Water and wastewater treatment
- Oils and lubricants
- Sludge and light slurry transfer
- Tank unloading
- Filtration systems
- Adhesives and sealants
- Mining support processes
- Marine and utility duties
- General industrial circulation
For example, a stainless-steel configuration may suit compatible corrosive liquids. Alternatively, ductile iron may suit selected abrasive or heavy-duty applications.
Selecting a Bolted Metal AODD Pump
Correct selection depends on:
- Required flow rate
- Discharge pressure
- Liquid composition
- Viscosity and temperature
- Solids size and concentration
- Body material
- Diaphragm and valve materials
- Available air pressure and volume
- Suction conditions
- Required thread standard
Therefore, users should configure the Wilden PS420 Bolted Metal Pump around the complete system duty. Otherwise, incompatible materials or insufficient compressed-air capacity may reduce performance and component life.
