Thank you for your interest in Water Pumps Direct. Before I can really make an educated suggestion on what pump you would need for your application, I would need to know the following specifications and requirements:
Depth of your well - 405 feet
Standing Water Level
Well Recovery Rate or Pumping Water Level
GPM & PSI Requirements
Total pumping distance including any elevation variance
Number of Sprinkler Heads (if zoned, per zone) And Their Individual GPM & PSI Requirements (if applicable)
Total Distance from The Pump to The Furthest Sprinkler and Any Elevation Variance (if applicable)
If you can supply this information, I'll be happy to assist you further.
