Air-Operated Double-Diaphragm Pneumatic Pump, Nitrile Seals

Brief Overview

This air-operated double-diaphragm pneumatic pump delivers dependable fluid transfer for industrial and workshop applications. The dual-chamber design ensures consistent flow with minimal pulsation, while the nitrile internal diaphragms provide excellent resistance to oils, solvents, and common industrial fluids. Built from die-cast metal construction with a sturdy mounting base, this pump is engineered for stationary installation in high-frequency transfer operations.

Key Features

• Double-Diaphragm Design: Two synchronized chambers deliver steady flow with reduced pulsation compared to single-chamber alternatives
• Nitrile Seals: Internal diaphragm material resists oils, mineral spirits, and industrial solvents—ideal for automotive fluid transfer
• Air-Operated: Pneumatic actuation with central air valve block eliminates the need for electric power
• Die-Cast Metal Housing: Aluminum or equivalent construction provides durability and corrosion resistance
• Flanged Port Connections: Molded inlet/outlet ports on sides and bottom accommodate standard industrial hose fittings
• Stable Mounting Base: Two flat feet with bolt holes for secure bench or floor installation
• Flow Direction Marked: Cast arrows indicate fluid path for straightforward installation

Business Advantages for Resellers

• High Turnover Item: Double-diaphragm pumps are consumables in busy shops—regular replacement cycles mean repeat orders
• Broad Application Base: Automotive, hydraulic, and fluid-transfer markets all demand these units
• Competitive Pricing Tier: Nitrile-seal pumps occupy the mid-range price point—strong margin potential without premium positioning
• Easy Integration Sales: Pairs naturally with pneumatic hoses, quick-connect fittings, and air-control accessories
• Low Return Rate: Proven design with minimal field failures when matched to appropriate fluid types
