First Pump® Horizontal Multistage Pumps
First Pump® Horizontal Multistage Pumps are high-efficiency centrifugal pumps designed for demanding industrial, municipal, and commercial applications. Engineered with a modular, multi-stage sectional design, these pumps deliver exceptional performance across a wide range of flow rates (3.75–1350 m³/h) and heads (up to 1725 meters). Their versatility allows them to handle clean water, seawater, chemicals, corrosive liquids, and abrasive media by tailoring materials and sealing systems.
Key Design Features
Modular Construction: Enables easy customization, maintenance, and interchangeability of components.
Robust Hydraulics: High-efficiency impellers ensure energy savings, low noise, and stable operation.
Axial Thrust Balancing: Dual-end bearings and balancing disks minimize axial load for extended lifespan.
Sealing Flexibility: Choose between traditional packing or advanced mechanical seals for leak-free performance.
Durable Materials:
◦ Standard: Bronze, Cast Iron, Carbon Steels.
◦ Corrosion-Resistant: 316/317 Stainless Steel, Duplex 2205, Super Duplex 2507.
◦ Exotic Alloys: Super Austenitic (254 SMO, 654 SMO), HASTELLOY® variants, Titanium grades.
Adaptable Configurations: Vertical or horizontal discharge ports; clockwise rotation (viewed from motor).
Product Series & Specializations:
Series | Key Applications | Fluid Compatibility | Temperature Range |
D | Municipal water, irrigation, mining | Clean water, mild abrasives | ≤80°C |
DG | Boiler feed, hot water systems | High-temperature water | ≤250°C |
DM | Mining, steel, wastewater | Slurries (≤1.5% solids, ≤0.5mm grains) | ≤80°C |
DF | Chemical, pharmaceutical industries | Corrosive liquids | -20°C to 150°C |
DY | Oil, fuel transfer | Viscous fluids (≤120 cSt) | -20°C to 150°C |
QD | Seawater, desalination, marine | Saline/abrasive liquids (≤1% solids) | Customizable |
Performance Highlights
Flow Range: 3.75 to 1350 m³/h
Head Range: Up to 1725 meters
Power: 4 to 4500 kW (electric motor-driven via elastic pin coupling).
fficiency: Up to 85% (varies by model and application).
NPSHr: As low as 2 meters for critical suction conditions.
Applications
Water Management: Municipal supply, irrigation, wastewater, cooling systems.
Industrial Processes: Mining (SX/EW, tailings), oil/gas (onshore/offshore), pulp/paper, steel production.
Chemicals & Energy: Solvent extraction, boiler feed, refinery operations.
Marine & Infrastructure: Seawater handling, firefighting, high-rise water supply.
Advantages
Reliability: Sliding or rolling bearings with grease/oil lubrication ensure smooth operation.
Customization: Adjust stages or trim impellers to match system requirements without redesign.
Low Maintenance: Replaceable shaft sleeves, accessible rotor assemblies, and modular sections reduce downtime.
Wide Compatibility: From -20°C cryogenics to 250°C boiler feed, with material options for aggressive media.
