DLX single injectors are designed specifically for cyclic operation oil systems and are intended to be used only in one direction.
Typically, they are installed near application points and connected to bearings.
Multiple Injector
The multiple injectors are accurate, positive displacement injectors. They provide precise lubrication for various applications. Their released lubricant’s capacity eliminates the risk of over- or under-lubrication. They run continuously, even under high pressure. When pressure drops, they refresh with fresh lubricant. Their key features are compatibility with many other series injectors, the ability to handle oil and soft greases, variable output volumes, a modular design, and optional push-to-connect fittings. A compatible pump must provide about 68 bar (1000 psi) of pressure to operate the system. A pressure relief valve is also needed to control line tension between cycles. The injectors can be attached to manifolds or tee fittings. Both compression-style and push-to-connect outlet fittings are available.
SL Injector
The FL injectors, single-line, and parallel grease have higher outputs. They are well-suited for the lubrication needs of medium and large machines. Additionally, their elevated output pressures make them ideal for harsh operating environments. The FL injectors have several key features. They have standard Viton O-rings. These protect against high heat and synthetic lubricants. They are compatible with major competing brands in form, fit, and function. All injectors come with vinyl cover caps. They have an adjustable oil output and a visual indicator pin for easy monitoring. They also include a feed line fill fitting for convenient setup.
