Product Description
Wilden PS220 Bolted Metal Pump
The Wilden PS220 Bolted Metal Pump is a 25 mm (1-inch) air-operated double-diaphragm pump developed for demanding industrial fluid-transfer duties.
Its FIT bolted construction provides strong product containment, while the enhanced liquid path improves hydraulic performance. Moreover, the Pro-Flo SHIFT air distribution system helps reduce unnecessary compressed-air use during operation.
PS220 AODD Pump Flow Performance
Maximum published flow depends on the selected diaphragm:
- TPE diaphragm: Up to 212 lpm
- Rubber diaphragm: Up to 204 lpm
- Full-Stroke PTFE diaphragm: Up to 197 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
- 25 mm or 1-inch liquid inlet and discharge
- 1/2-inch FNPT compressed-air inlet
- Maximum flow up to 212 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
- Multiple wetted-body materials
- Rubber, TPE and PTFE diaphragm options
- Strong dry and wet suction lift
- Compatible clamped-pump footprint
- Improved diaphragm life
- Simplified operation and maintenance
Together, these features make the Wilden PS220 Bolted Metal Pump suitable for varied industrial transfer, circulation and unloading requirements.
FIT Bolted Metal Pump Construction
The FIT design uses bolted liquid chambers and manifolds to provide secure containment. Therefore, it supports applications where reliable sealing and reduced leakage risk are important.
Wilden also 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 piping or foundation changes.
Pro-Flo SHIFT Air System
The Pro-Flo SHIFT system controls compressed-air delivery near the end of each diaphragm stroke. As a result, it reduces unnecessary filling of the air chamber while maintaining the pumping cycle.
Moreover, Wilden states that Pro-Flo SHIFT pumps can provide substantial energy savings, improved flow and fewer operating parts than conventional designs. Consequently, users may reduce air consumption, maintenance requirements and downtime.
Threaded PS220 Pump Connections
The Wilden PS220 Bolted Metal Pump uses 1-inch NPT or BSPT threaded liquid connections. Therefore, it suits installations requiring threaded suction and discharge piping.
In contrast, the related PS230 uses DIN or ANSI flanged connections. Consequently, users should verify the required pipe standard before ordering.
Metal Body and Elastomer Options
Available wetted-body materials include:
- Aluminium
- Ductile iron
- Stainless steel
- Alloy C
Moreover, available elastomers include Buna-N, EPDM, FKM, Geolast, Neoprene, PTFE, polyurethane, Saniflex and Wil-Flex. Therefore, users can configure the pump around chemical resistance, abrasion, temperature and flexibility requirements.
However, diaphragm life depends on more than basic chemical compatibility. Process temperature, abrasiveness, suction lift and operating conditions also affect service life.
Solids Handling and Suction Lift
The pump passes solids up to 6.4 mm or 1/4 inch in diameter. Consequently, it can handle compatible liquids containing limited suspended particles.
Maximum dry suction lift is:
- Rubber: 6.9 m
- TPE: 5.9 m
- Full-Stroke PTFE: 5.2 m
Meanwhile, maximum published wet suction lift reaches 9 metres. However, actual suction performance depends on viscosity, piping losses, elevation and operating speed.
UAE Applications for the PS220 Pump
The Wilden PS220 Bolted Metal Pump may support:
- Chemical transfer
- Paint and coating production
- Resin and solvent transfer
- Water and wastewater treatment
- Oil and lubricant handling
- Tank unloading
- Filtration systems
- Adhesives and sealants
- General industrial circulation
- Fluids containing suspended particles
- Portable transfer duties
- Corrosive-liquid handling
For example, Wilden identifies Pro-Flo SHIFT metal pumps for paints, coatings and industrial applications requiring containment, low-shear handling and simplified maintenance.
Selecting a Wilden PS220 Pump
Correct selection depends on:
- Required flow rate
- Discharge pressure
- Liquid composition
- Viscosity and temperature
- Solids size and concentration
- Wetted-body material
- Diaphragm and valve materials
- Available compressed-air supply
- Suction conditions
- Required thread standard
Therefore, users should configure the Wilden PS220 Bolted Metal Pump according to the complete system duty. Otherwise, incompatible materials or insufficient air volume may reduce flow and component life.
Why Choose the PS220 Bolted Metal AODD Pump?
The PS220 combines compact 1-inch connections, secure bolted containment and efficient pneumatic operation. Moreover, its matching footprint can simplify replacement of compatible Wilden clamped pumps.
As a result, it provides a practical option for UAE facilities requiring reliable chemical transfer, strong suction capability and broad material flexibility.
