Product Description
Wilden PS820 Bolted Metal Pump
The Wilden PS820 Bolted Metal Pump is a 51 mm (2-inch) air-operated double-diaphragm pump designed for industrial fluid transfer. Its Pro-Flo SHIFT air system, FIT bolted construction and optimised flow path support dependable containment, strong flow and reduced compressed-air demand.
The threaded PS820 model provides NPT or BSPT liquid connections. In contrast, the related PS830 uses DIN or ANSI flanged connections. Maximum published flow reaches 685 lpm, while maximum discharge pressure is 8.6 bar.
PS820 AODD Pump Performance
The pump uses an enhanced liquid path to reduce unnecessary restrictions. Consequently, Wilden states that the FIT design can provide flow rates up to 35% higher than competing models.
Moreover, the PS820 delivers up to 685 lpm with rubber diaphragms, 668 lpm with EZ-Install TPE, and 655 lpm with Full-Stroke PTFE. Therefore, users can select the elastomer according to the required flow, chemical compatibility and operating conditions.
Key Features
The Wilden FIT pump provides several practical advantages:
- 51 mm or 2-inch liquid inlet and discharge
- 3/4-inch FNPT air inlet
- Maximum flow up to 685 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 options
- Portable and submersible capability
- Strong suction-lift performance
- Matching footprint for compatible clamped pumps
Together, these features make the Wilden PS820 Bolted Metal Pump suitable for chemicals, oils, coatings, wastewater and fluids containing suspended particles.
FIT Bolted Metal Construction
The FIT design uses bolted liquid chambers and manifolds to support secure product containment. Therefore, it provides a robust alternative to clamped assemblies where leak prevention is important.
Wilden also designed the pump with the same bolt-down footprint and connection positions as compatible clamped pumps. Consequently, facilities can replace an existing model without extensive piping or foundation changes.
Available metal body options include:
- Aluminium
- Ductile iron
- Stainless steel
Therefore, engineers can select the construction according to corrosion resistance, abrasion and fluid compatibility.
Pro-Flo SHIFT Air Distribution System
The pump includes the Pro-Flo SHIFT air distribution system. It controls airflow near the end of each stroke and limits unnecessary overfilling of the air chamber.
As a result, the pump can reduce compressed-air use without reducing flow. Wilden states that the Pro-Flo SHIFT platform can provide air savings of up to 60% compared with conventional diaphragm-pump technology.
Moreover, the simplified air system can support lower operating costs and longer service intervals when maintained correctly.
Threaded Two-Inch Connections
The PS820 uses 2-inch NPT or BSPT threaded inlet and discharge connections. Therefore, it suits installations where threaded process connections are preferred.
In contrast, the related PS830 uses DIN or ANSI flanges. Consequently, users should confirm the required connection standard before ordering.
Diaphragm and Suction Options
The Wilden PS820 Bolted Metal Pump supports rubber, EZ-Install TPE and Full-Stroke PTFE diaphragms.
Published maximum dry suction lift is approximately:
- 7.1 metres with rubber diaphragms
- 7.0 metres with TPE diaphragms
- 6.6 metres with PTFE diaphragms
Meanwhile, maximum wet suction lift reaches approximately 9.0 metres across the published configurations.
Therefore, diaphragm selection should consider chemical resistance, temperature, abrasion, suction conditions and expected service life.
Solids-Handling Capability
The pump can pass solids up to 6.4 mm or 1/4 inch. Consequently, it may handle compatible fluids containing particles that could obstruct equipment with narrower internal passages.
However, actual performance also depends on particle shape, concentration, fluid viscosity and pumping speed. Therefore, users should provide complete fluid details during technical selection.
Wilden PS820 Applications in India
The PS820 AODD pump may suit many industrial applications across India, including:
- Chemical transfer
- Paints and coatings
- Oil and lubricant handling
- Water and wastewater treatment
- Sludge and light slurry transfer
- Tank unloading
- Marine and utility duties
- Mining support operations
- Ceramic-processing liquids
- Portable dewatering
- Fluids containing suspended particles
- General industrial transfer
For example, a coating facility can select compatible wetted materials for pigments or resins. Similarly, a wastewater plant can use the pump for suitable liquids containing suspended solids.
Selecting the Correct Wilden PS820 Pump
Correct selection depends on:
- Required flow rate
- Discharge pressure
- Fluid 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 pump for the complete operating duty. Otherwise, incompatible materials or insufficient compressed air may reduce performance, reliability and component life.
Why Choose the PS820 Bolted Metal AODD Pump?
This Wilden FIT pump combines efficient pneumatic operation, secure bolted containment and broad material flexibility. Moreover, its matching footprint simplifies the replacement of compatible Wilden clamped pumps.
As a result, it is a practical option for facilities across India that require reliable two-inch fluid transfer, strong suction capability, solids handling and reduced compressed-air consumption.
