Product Description
Wilden P4 Clamped Metal Pump for Industrial Transfer
The Wilden P4 Clamped Metal Pump is a 38 mm (1½-inch) air-operated double-diaphragm pump designed for general industrial and process-fluid applications. Its rugged metal construction supports dependable operation in demanding environments.
Moreover, the clamp-band design provides quick access to internal components. Consequently, technicians can complete inspections, cleaning and routine maintenance with less dismantling time.
Wilden P4 Metal Pump Flow and Pressure
Maximum published flow depends on the selected diaphragm:
- Rubber: Up to 288 lpm
- TPE: Up to 307 lpm
- Full-Stroke PTFE: Up to 330 lpm
- Reduced-Stroke PTFE: Up to 295 lpm
- Ultra-Flex: Up to 269 lpm
In addition, maximum discharge pressure reaches 8.6 bar or 125 psi. However, actual performance depends on compressed-air volume, discharge pressure, fluid viscosity and system resistance.
Therefore, users should select the P4 AODD pump from the appropriate performance curve rather than relying only on the maximum flow figure.
Key Features and Benefits
The Wilden Pro-Flo metal pump provides:
- 38 mm or 1½-inch liquid inlet
- 32 mm or 1¼-inch liquid discharge
- ½-inch FNPT compressed-air inlet
- Maximum flow up to 330 lpm
- Maximum pressure of 8.6 bar
- Solids passage up to 4.8 mm
- NPT or BSPT threaded connections
- Four metal housing options
- Multiple diaphragm materials
- Clamp bands for faster servicing
- Strong wet and dry suction capability
- Lube-free pneumatic operation
- Simple installation and maintenance
Together, these features make the Wilden P4 Clamped Metal Pump suitable for transfer, circulation, dewatering and compatible fluids containing suspended particles.
Pro-Flo Air Distribution System
The P4 metal AODD pump uses the Pro-Flo Air Distribution System for dependable pneumatic cycling with a simplified internal design. Consequently, the pump supports reliable starting and stopping during intermittent or continuous operation.
Moreover, the plastic centre section operates without external airline lubrication. Therefore, facilities can reduce lubricator maintenance and avoid introducing lubricant into the compressed-air exhaust.
As a result, the Wilden P4 pump provides straightforward pneumatic operation for varied industrial transfer duties.
Clamped Metal Pump Maintenance
Clamp bands secure the manifolds, liquid chambers and centre section. Consequently, technicians can dismantle and reassemble the pump using a single tool.
Moreover, quick access to diaphragms, valve balls and valve seats can reduce planned maintenance time. Therefore, the Wilden P4 Clamped Metal Pump is particularly suitable for installations where frequent inspection, cleaning or servicing is required.
Wilden P4 Metal Housing Options
The P4 metal pump is available in:
- Aluminium: Lightweight construction for compatible general industrial liquids
- Cast iron: Robust construction for selected abrasive and utility duties
- Stainless steel: Corrosion resistance for many compatible chemicals and process liquids
- Alloy C: Enhanced resistance for selected aggressive chemical applications
However, no material is universally compatible. Therefore, users should verify the liquid composition, concentration, operating temperature and abrasiveness before selecting the pump.
Diaphragm and Elastomer Options
The P4 AODD pump supports:
- Rubber diaphragms
- TPE diaphragms
- Full-Stroke PTFE diaphragms
- Reduced-Stroke PTFE diaphragms
- Ultra-Flex diaphragms
Available elastomer materials may include:
- Buna-N
- EPDM
- FKM
- Neoprene
- PTFE
- Polyurethane
- Saniflex
- Wil-Flex
Each material provides different chemical, temperature, flexibility and abrasion characteristics. Consequently, the diaphragms, valve balls, valve seats and seals should all match the transferred fluid and operating conditions.
Threaded P4 Pump Connections
The Wilden P4 Clamped Metal Pump uses a 1½-inch threaded inlet and a 1¼-inch threaded discharge. NPT and BSPT connection standards are available.
Therefore, the pump can integrate with varied industrial piping and hose systems. However, users should confirm both connection sizes, the required thread standard and compatible sealing material before installation.
Solids Handling and Suction Lift
The Pro-Flo P4 can pass compatible solids up to 4.8 mm or 3/16 inch. As a result, it may transfer selected fluids containing suspended particles.
Maximum published dry suction lift reaches:
- Rubber: Up to 5.8 metres
- TPE: Up to 5.2 metres
- Full-Stroke PTFE: Up to 6.4 metres
- Reduced-Stroke PTFE: Up to 3.7 metres
- Ultra-Flex: Up to 5.2 metres
Meanwhile, wet suction lift reaches up to approximately 9.3 metres.
However, liquid viscosity, inlet restrictions, installation elevation, compressed-air capacity and operating speed affect actual suction performance.
Wilden P4 Applications in India
The Wilden P4 Clamped Metal Pump may support industrial applications across India such as:
- Industrial dewatering
- Paints and coatings
- Ceramic slurry transfer
- Chemical processing
- Water and wastewater treatment
- Tank and container unloading
- Oils and lubricants
- Adhesives and sealants
- Mining support processes
- General industrial circulation
For example, an aluminium P4 pump may suit compatible coatings and utility fluids. Alternatively, stainless steel or Alloy C configurations may support selected corrosive chemicals after a complete material-compatibility review.
Similarly, cast-iron construction may suit suitable abrasive or heavy-duty transfer duties.
Selecting the Correct Wilden P4 Pump
Correct selection depends on:
- Required flow and discharge pressure
- Fluid composition and concentration
- Operating temperature
- Liquid viscosity
- Abrasiveness
- Solids size and concentration
- Wetted housing material
- Diaphragm and valve materials
- NPT or BSPT connection standard
- Suction conditions
- Available compressed-air pressure and volume
Therefore, users should configure the Wilden P4 Clamped Metal Pump around the complete hydraulic and process duty.
Otherwise, incompatible materials may cause premature wear. Similarly, insufficient compressed-air capacity or unsuitable suction conditions may reduce flow, efficiency and component life.
