The NP400 LLPS has a small control panel and low level switching module added to the NP400PP puddle pump that will give safe switching of water levels of just 10mm. Switching of puddle pumps is problematic because by their nature they are dealing with low heights of water.
This makes conventional switching difficult. The NP400 LLPS has a small control panel and low level switching module added to the NP400PP puddle pump that will give accurate and safe switching of water levels of just 10mm. The NP400 LLPS will pump down to just 1mm of water depth.
