Applications
Overview
The ASTROLABE SPA530 is a professional submersible electric pump built around a die-cast aluminum alloy housing that functions like an integrated water tank — enabling reliable continuous-duty operation even when water levels drop. A foot-valve seat drains residual water, while the float switch fully automates start and stop cycles. Built-in overheating and overcurrent motor protectors instantly interrupt power if operating limits are exceeded, extending pump life and safeguarding the installation. Rated for water with up to 0.2 mm suspended solids, pH 6.5–8.5, and continuous submersion to 5 m, the SPA530 is the workhorse choice for households, aquaculture, municipal works, and light industrial dewatering.
