Mega Pumps’ patented Self-Sealing Actuator system is ideal for precision dose dispensing of lotions, creams, gels, ointments and emulsions. It protects products from impurities and contamination through a membrane in the pump’s orifice that automatically seals once the formula has been dispensed. This prevents the product from coming into contact with oxygen, thereby reducing contamination, discoloration and product dry-out, and ultimately, increasing shelf life and effectiveness. The all-plastic, self-priming system allows for dispensing in any position and delivers precise, repeatable doses. The Self-Sealing Actuator is available in the company’s Mezzo, Mini, Midi and Macro models, in round or oval shaped containers, ranging in size from 30-200ml.
