Pump Primer (Concrete Pump Hose Primer) is used to prime concrete pumps and pipes for pressure reduction and capacity improvement. Supplied as an efficient replacement of traditional cement slurry. It is a unique compound of high-performance components. Offering big cost reductions by saving time and protecting concrete pumps and pipes. Pump primer eases pressure in the pump and pipes. It also optimizes pump capacity when using “sticky” concrete mixes.
