*1. Cannot be used with seawater and special liquid.
Features
*1. Cannot be used with seawater and special liquid.*2. Compliant with ASTM Standards (set by ASTM International) and equivalent to SCS6.
• Low power consumption due to the higher efficiency.• The specially designed impeller of the first stage achieves low NPSHR to prevent cavitation.• The pump structure has the degree of freedom in nozzle arrangement, which allows the suction and discharge directions
to be changed freely. LiquidSuction requirmentAllowable suction pressure
