Designed with food processors in mind, Saniflo Hygienic Series pumps offer the ease of maintenance, cleanability, portability, dead-head capable and self-priming attributes that are critical in several applications found within food operations. The pumps have been designed specifically to meet the needs of both mainstream and specialized sanitary/hygienic applications. The most basic configurations offer high polish, flow-through liquid chamber design and no hidden areas in the check-valve seat area. Advanced configurations include integral piston PTFE diaphragms, a diaphragm-monitoring system and a swivel stand that permits drainability. The pumps are also equipped with the patent-pending air distribution system (ADS), which provides reliable operation, high flow rates and superior anti-freezing characteristics.
