NOMAD PWR-FLO NPF50 flap valve 2" conductive polypropylene Neoprene-fitted air-operated double diaphragm pump, clamped (MPN 50-4263)

Description

The NOMAD Pwr-Flo NPF50 Flap Valve (model 50-4263) is a 2" (51 mm) conductive polypropylene, Neoprene-fitted air-operated double diaphragm (AODD) pump that runs on up to 125 psig (8.6 bar) of compressed air. This clamped, NPT-ported standard build is a Pwr-Flo pump built for indoor plant service on clean, filtered air, with an anti-stall ASD air valve for on/off filling and batching.

Conductive (carbon-filled) polypropylene wetted parts let the pump body be grounded, which is commonly required where static build-up must be controlled. Neoprene is a general-purpose rubber with good abrasion resistance, commonly used for water-based slurries and non-aggressive fluids. Always confirm chemical compatibility with your fluid before ordering - Tank Supply Direct can check it for you. Full performance data for this build is in the NOMAD operation manual linked below.

Key Features

• Asymmetrical spool design (ASD) air valve
• Anti-stall design for reliable on/off filling and batching
• Air-efficient operation on clean, filtered air
• Conductive Polypropylene wetted parts, Neoprene diaphragms - standard NOMAD build 50-4263
• Clamped construction - quick teardown for diaphragm and check-valve service
• Air-operated, no electric motor - flow adjusts with the air supply; no motor or controls at the pump

Applications

NOMAD lists these industries for this pump: Automotive, Ceramics, Chemical, electronics/semiconductor, Food/Beverage, Mining/Construction, Petroleum, Pharmaceutical, Wastewater.

Pwr-Flo or Trans-Flo? NOMAD positions Pwr-Flo for indoor plant and factory service on clean, filtered air. Its ASD air valve is the more air-efficient design and gives reliable on/off starts for filling and batching.

Common Questions

What does "Neoprene-fitted" mean, and when should I choose a different material?
The diaphragms and check balls are Neoprene. Neoprene is a general-purpose rubber with good abrasion resistance, commonly used for water-based slurries and non-aggressive fluids.

What air supply does it need?
Connect clean, dry compressed air; do not exceed 125 psig (8.6 bar). Flow and discharge pressure rise and fall with the air pressure you supply.

Is this pump available in other configurations?
Yes. NOMAD also builds this model with other port connections (BSP). This listing is the standard build; call or email Tank Supply Direct for a quote on any other configuration.

How fast does it ship?
The standard build ships from Nevada in approximately 4 days. Shipping is calculated at checkout.
