- What are Pumps?
- Pumps move fluids throughout vessel systems for various applications including ballast, fire fighting, bilge, cooling, and cargo transfer. Common types include Centrifugal Pumps (for high flow; low viscosity applications; with Service specification for Ballast; Fire; Bilge; Cooling; General) and Positive Displacement Pumps (for viscous fluids and precise flow control; available as Screw; Gear; or Lobe type).
- What are the different types of Pumps?
- Common types include Centrifugal Pumps, Positive Displacement Pumps, Submersible Pumps.
- What standards apply to Pumps?
- Products in this category typically reference ISO 9906:2012 (Centrifugal) and API 676 (Positive Displacement). Specific requirements may vary by application and classification society.
- Buyer requirements
- Procurement typically requires Flow Rate (m³/h) and Head (m) for centrifugal pumps, or Flow Rate (m³/h) and Differential Pressure (bar) for positive displacement pumps to match system design requirements. For centrifugal pumps, Service (Ballast; Fire; Bilge; Cooling; General), Material (Bronze; Cast Iron; Stainless – critical for service compatibility; seawater typically requires bronze or stainless), Motor Power (kW), Seal Type, and Voltage/Frequency are critical. For positive displacement pumps, Type (Screw; Gear; Lobe), Material, Viscosity Range (cSt), Motor Power (kW), and Port Size are critical for system compatibility.
