Aluminum pump body – lightweight, good for clean water, light debris, and weak corrosive liquids. Ideal for portable use (e.g., flood relief, irrigation).Cast iron pump body – robust, handles dirty water, sand, oil, seawater, and industrial fluids. Suitable for stationary or heavy-duty applications.

Suction Side Issues:· Clogged Strainer or Foot Valve: The intake filter is blocked by debris.· Air Leaks: Cracks or loose connections in the suction hose pipe allowing air to enter.· Insufficient Water Source: Water level is too low, or the source is depleted.· Excessive Suction Head: The pump is pl

What are Flow & Head?· Flow (or Discharge): The volume of water the pump can move per unit of time. Typically measured in Liters per Minute (L/min) or Cubic Meters per Hour (m³/h). · Think: "How much water?"· Head (Total Head): The total height the pump can push water against gravity, plus the energ

Focus on these key factors:1. Application: What is the primary task? (e.g., flood drainage, irrigation, construction dewatering).2. Performance: Match the pump's Flow and Head to your job's requirements.3. Engine: Look for a reliable, air-cooled diesel engine, like Siwei Power:)4. Solid Construction

It uses a specially designed pump casing that creates an air-water mixture.1. Initial Priming: The pump casing is pre-filled with a small amount of water ("priming water").2. Air Removal: When started, the impeller churns this water, creating a vortex that mixes with the air from the suction hose.3.
