perma FLEX is designed to match the programmed discharge period when there is no counter pressure at the lube-point. The higher the counter pressure (caused by tight lube channels or long tube connections), the longer the discharge period. To ensure proper operation, we recommend to measure the counter pressure at the lube-point.

Low temperatures = slower discharge 
Higher temperatures = faster discharge

Important: If the ambient temperature permanently exceeds + 40°C / 140 °F, the selected discharge period must not be longer than 6 months.
