Filters – A grease filter is strongly recommended when pumping from a pail or barrel. Metal chips, foreign particles, and other debris can get into the grease, and if not filtered out, they can jam up the dispensing system, or even worse, they can become a part of your product.
Regulators – Some dispensers require a low pressure less than 200 psi grease supply. Because most air-operated pumps can not supply grease at low pressure, a grease pressure regulator or auto-fill reservoir is often needed to reduce the supply pressure to the dispenser(s).
Accessories – A ball valve to shut off the grease supply ahead of the filter makes it easier to check and clean the filter element. A pressure gauge is needed to confirm the regulator setting.
