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 supports secure product containment, while the enhanced liquid path improves hydraulic performance. Moreover, the Pro-Flo SHIFT air distribution system helps reduce unnecessary compressed-air consumption 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, operating temperature, suction requirements and required output.
Key Features and Benefits
The Wilden FIT pump provides:
- 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 capability
- Compatible clamped-pump footprint
- Improved diaphragm life
- Simplified operation and maintenance
Together, these features make the Wilden PS220 Bolted Metal Pump suitable for industrial transfer, circulation, unloading and chemical-handling duties.
FIT Bolted Metal Construction
The PS220 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.
This compatibility can help reduce installation time when upgrading an existing air-operated diaphragm pump system.
Pro-Flo SHIFT Air System
The Wilden PS220 Bolted Metal Pump uses the Pro-Flo SHIFT air distribution system to control compressed-air delivery near the end of each diaphragm stroke.
As a result, the system limits unnecessary filling of the air chamber while maintaining the required pumping cycle. Moreover, Wilden states that Pro-Flo SHIFT pumps can support improved flow, lower air consumption and fewer operating components than conventional designs.
Consequently, users may reduce energy consumption, maintenance requirements and unplanned downtime.
Threaded PS220 Pump Connections
The PS220 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 piping standard before selecting the pump.
Metal Body and Elastomer Options
Available wetted-body materials include:
- Aluminium
- Ductile iron
- Stainless steel
- Alloy C
Available elastomer options include:
- Buna-N
- EPDM
- FKM
- Geolast
- Neoprene
- PTFE
- Polyurethane
- Saniflex
- Wil-Flex
Therefore, the PS220 AODD pump can be configured according to chemical resistance, abrasion, temperature and flexibility requirements.
However, diaphragm life depends on more than basic chemical compatibility. Process temperature, abrasiveness, suction lift, operating speed and air pressure also affect service life.
Solids Handling and Suction Lift
The Wilden PS220 Bolted Metal Pump can pass solids up to 6.4 mm or 1/4 inch in diameter. Consequently, it may handle compatible liquids containing limited suspended particles.
Published maximum dry suction lift is:
- Rubber diaphragm: 6.9 metres
- TPE diaphragm: 5.9 metres
- Full-Stroke PTFE diaphragm: 5.2 metres
Meanwhile, maximum wet suction lift reaches approximately 9 metres.
However, actual suction performance depends on fluid viscosity, piping losses, installation elevation, air supply and operating speed.
Wilden PS220 Applications in India
The PS220 bolted metal pump may support applications across India such as:
- 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, a stainless-steel or Alloy C configuration may support suitable corrosive liquids. Similarly, an aluminium or ductile-iron model may suit compatible coatings, lubricants or general industrial fluids.
Selecting the Correct Wilden PS220 Pump
Correct selection depends on:
- Required flow rate
- Discharge pressure
- Liquid composition
- Fluid viscosity and temperature
- Solids size and concentration
- Wetted-body material
- Diaphragm and valve materials
- Available compressed-air pressure and volume
- Suction conditions
- Required thread standard
Therefore, users should configure the Wilden PS220 Bolted Metal Pump according to the complete hydraulic and chemical duty.
Otherwise, incompatible materials, excessive suction lift or insufficient compressed-air volume may reduce flow, reliability 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 broad material options support varied industrial fluids, while its matching footprint can simplify the replacement of compatible Wilden clamped pumps.
As a result, the Wilden PS220 provides a practical solution for facilities across India requiring reliable chemical transfer, strong suction capability and flexible material selection.
