AutoPump - Model AP4.5 Ultra - High-Clearance Pump - Brochure

The new AutoPump AP4.5 Ultra (Patent Pending) delivers superior  performance, running many times longer between service events. A pump installed for field testing needed just 30 minutes to clean after 220,000 minutes (348,965  cycles!) of uninterrupted run time – in a well that had been out of compliance for the previous 3 years, requiring pump cleaning every 3 to 5 days.
