JetStream™ AJS/2004 Diaphragm PumpThe JetStream AJS/2004 is a vacuum-operated diaphragm pump designed for teat spray and liquid transfer in dairy and livestock systems. Compact and durable, it delivers consistent spray performance, even with multiple spray guns in use. Constructed from chemical-resistant polypropylene and EPDM, it ensures long service life and easy maintenance. Optional Viton models are available for use with chlorine dioxide or lactic acid. Lightweight, efficient, and electricity-free, the JetStream AJS/2004 is the reliable choice for farm hygiene and fluid handling applications.
The JetStream™ AJS/2004 diaphragm pump offers a robust, vacuum-operated solution for teat spray and liquid transfer systems—especially in dairy and livestock environments. Designed for reliability, ease-of-use, and broad chemical compatibility, the AJS/2004 delivers consistent performance with minimal maintenance.
Key Features & Benefits
Vacuum-driven operation — No electricity required, making it ideal for remote or off-grid installations.
High capacity & consistent pressure — Maintains spray output even when multiple spray guns operate simultaneously.
Chemical compatibility — Built to handle a wide range of fluids; for harsher chemicals like chlorine dioxide and lactic acid, a Viton-model variant is available.
Durable construction — Components include: • Pump head in polypropylene • Non-return valves composed of polypropylene and glass balls • Pump body in polyphenol ether (PPE) • Diaphragms in EPDM with bonded or welded steel elements • O-rings in EPDM or optional Viton
Modular, serviceable design — Key parts (inlet valve, outlet valve, diaphragm) are available as spare components.
Compact & lightweight — Measures ˜ 22 × 15 × 18 cm and weighs ~1.4 kg.
British manufacture — Engineered and produced in the UK, supporting quality assurance and supply chain reliability.
Typical Applications
Dairy and livestock teat spray systems (pre- and post-milking)
Hygienic spray systems in agricultural settings
Liquid distribution tasks in remote or low-power environments
Use in settings where vacuum-based fluid transfer is preferred
Restrictions & Notes
Not suitable for use with sodium hypochlorite or peracetic acid
For applications involving chlorine dioxide or lactic acid, the Viton-model variant should be considered
Ensure the pump is matched with compatible materials and fluid properties to optimize lifespan and performance
