Dewater and pump floods
Flooded trench, basement after the storm or continuous groundwater control: the right pump is chosen by flow and total head. SIMAQ 3" and 4" pumps move water with solids without choking.
Field rules
Do it right the first time
01
Compute total head: suction + discharge + hose losses. Nameplate flow drops fast with head.
02
Keep suction short and airtight: every extra meter on suction costs double what it costs on discharge.
03
Strainer always on: one wrong-size rock kills your impeller mid-emergency.
