Product Description

Wilden P1 Clamped Metal Pump for Industrial Transfer

The Wilden P1 Clamped Metal Pump is a compact 13 mm (½-inch) air-operated double-diaphragm pump for general industrial fluid transfer. Its rugged metal construction supports dependable operation in process equipment, utility systems and portable transfer applications.

Moreover, the clamp-band design gives technicians quick access to internal components. Consequently, the pump combines reliable performance with simple installation and efficient maintenance.

Wilden P1 Metal Pump Flow and Pressure

Maximum flow depends on diaphragm selection:

  • Rubber: Up to 58.7 lpm
  • TPE: Up to 58.3 lpm
  • PTFE: Up to 54.4 lpm

In addition, maximum discharge pressure reaches 8.6 bar or 125 psi. However, actual output depends on compressed-air volume, discharge pressure, viscosity and piping resistance.

Therefore, users should select the P1 AODD pump from the correct performance curve instead of relying only on the maximum flow figure.

Key Features of the P1 AODD Pump

  • 13 mm or ½-inch liquid inlet and discharge
  • ¼-inch FNPT compressed-air inlet
  • Maximum flow up to 58.7 lpm
  • Maximum pressure of 8.6 bar
  • Solids passage up to 1.59 mm
  • NPT or BSPT threaded connections
  • Aluminium or stainless-steel wetted housings
  • Rubber, TPE and PTFE diaphragm options
  • Clamp bands for faster servicing
  • Strong wet and dry suction capability
  • Pro-Flo Air Distribution System
  • Lube-free pneumatic operation
  • Simple installation and maintenance

Together, these features make the Wilden P1 Clamped Metal Pump suitable for compact transfer, circulation, sampling and container-unloading duties.

Pro-Flo P1 Air Distribution System

The Pro-Flo Air Distribution System uses a simplified design with only three moving parts. Consequently, the Wilden P1 metal pump supports dependable cycling and straightforward repair.

Moreover, the plastic centre section operates without external airline lubrication. Therefore, facilities can reduce lubricator maintenance and avoid introducing lubricant into the exhaust air.

Clamped Metal Pump Maintenance

Clamp bands secure the manifolds, liquid chambers and centre section. As a result, technicians can dismantle and reassemble the Pro-Flo clamped metal pump using a single tool.

Moreover, rapid access to diaphragms, valve balls and seats can reduce servicing time. Therefore, the P1 pump suits installations requiring frequent inspection, cleaning or component replacement.

Wilden P1 Metal Housing Options

The Wilden P1 Clamped Metal Pump is available with two wetted-housing materials:

  • Aluminium: Lightweight construction for compatible general industrial liquids
  • Stainless steel: Corrosion-resistant construction for many compatible chemicals and process fluids

However, neither metal suits every liquid. Therefore, users must verify chemical composition, concentration, operating temperature and abrasiveness before ordering.

P1 Diaphragm and Elastomer Options

The P1 AODD pump supports rubber, TPE and PTFE diaphragm configurations.

Moreover, official elastomer options include Buna-N, EPDM, FKM, PTFE, polyurethane, Saniflex and Wil-Flex. Each material provides different chemical, temperature and abrasion characteristics.

Consequently, the diaphragms, valve balls, seats and seals should all match the transferred fluid.

Half-Inch Threaded P1 Pump Connections

The Wilden P1 metal pump uses ½-inch NPT or BSPT threaded inlet and discharge connections. Therefore, it integrates easily with compact piping, flexible hoses and equipment skids.

In addition, threaded connections can simplify installation and disconnection. However, users should confirm the required thread standard and compatible sealing material before installation.

P1 Solids Handling and Suction Lift

The Pro-Flo P1 pump passes compatible solids up to 1.59 mm or 1/16 inch. As a result, it can transfer clean fluids and selected liquids containing small suspended particles.

Maximum dry suction lift reaches 5.8 m with rubber, 5.2 m with TPE and 4.9 m with PTFE. Meanwhile, maximum wet suction lift reaches 9.5 metres for all three diaphragm types.

However, viscosity, elevation, inlet restrictions and operating speed affect actual suction performance.

Wilden P1 Clamped Metal Pump Applications

The Wilden P1 Clamped Metal Pump may support:

  • Industrial dewatering
  • Paint and coating transfer
  • Ceramic-process liquids
  • Chemical sampling
  • Water-treatment chemicals
  • Drum and container unloading
  • Oils and lubricants
  • Equipment-skid circulation
  • Cleaning-fluid transfer
  • General industrial processes

For example, aluminium may suit compatible coatings, oils and utility fluids. Alternatively, stainless steel may support selected corrosive liquids after a complete compatibility review.

Selecting a Wilden P1 AODD Pump

Correct selection depends on flow, pressure, fluid composition, temperature, viscosity, abrasiveness and particle content.

In addition, users should confirm the housing, elastomers, thread standard, suction conditions and available compressed-air volume. Therefore, the Wilden P1 Clamped Metal Pump should be configured around the complete operating duty.

Otherwise, incompatible materials may cause premature wear. Similarly, insufficient air volume may reduce output and efficiency.

Why Choose the Wilden Pro-Flo P1?

The Pro-Flo P1 combines durable metal construction with rapid clamp-band servicing. Moreover, its compact size, dependable suction and multiple diaphragm materials support varied industrial requirements.

Consequently, this half-inch AODD pump provides a practical solution for UAE facilities requiring reliable low-flow transfer and straightforward maintenance.
