ARROW PRODUCT OVERVIEW
Series 500 chemical Pump
The Arrow Series 500 chemical injectors, engineered to precision specifications, are positive displacement units with integral gas motors. You will find the horizontal plunger and vertical resilient check valve arrangement will assure you of high operation efficiency.
The Arrow injectors fill the needs of a broad range of applications. They are capable of achieving extremely high discharge pressures of up to 12,000 psi and also a wide range of volumes. All the Arrow chemical injectors have a standard pump head with a steel body and 18-8 stainless steel trim. You can also order all stainless steel heads for those applications where the pumps will be operating in highly corrosive conditions. The built-in priming valve improves pump head priming, enabling you to easily check the pump operation. It also provides a sample catching device.
You will find the pump frame and body castings are constructed of the highest quality aluminum. To prevent any dust or other contaminants from entering the system, the operating mechanism operates in oil. The main diaphragm is protected against accidental overpressure with a safety valve, thus improving the operation of the Arrow injector. You will find that the adjustable packing, with the lantern ring and grease jack for lubricating the plunger, will provide consistent and reliable service. If you purchased the Arrow chemical injector with Teflon packing, no grease jack is furnished.
