marine vertical single stage pipeline centrifugal pump

The marine vertical single-stage pipeline centrifugal pump is engineered for installation in the narrow spaces of ships, offering durability, high efficiency, and quiet operation. Its vertical structure and compact design make it ideal for marine machinery compartments and piping systems.

1. Main Features

1. Vertical design: Space-saving structure for compact ship environments; easy to install directly in piping systems.
2. Single-stage impeller: Delivers high operating efficiency and stable performance, supporting continuous water supply needs.
3. Material preferences: Pump body and impeller made from stainless steel or bronze for corrosion resistance; wear-resistant shaft seal for long service life.
4. Quiet operation: Balanced, optimized design ensures low noise for improved crew working conditions.

2. Technical Parameters

1. Pump body: Cast iron, stainless steel
2. Impeller: Stainless steel
3. Shaft seal: Mechanical seal

3. Structure and Working Principle

1. Structure:
   • Pump body: Snail shell type design optimizes water flow and reduces energy loss.
   • Single-stage impeller for stable pressurization.
   • Shaft seal: Mechanical or packing seal for zero leakage.
   • Direct motor connection for efficient energy transfer and easy installation.
2. Working Principle:
   • Centrifugal force from impeller rotation draws in liquid and pressurizes it for discharge.
   • Vertical axis creates a more linear water flow path, lowering flow resistance.

4. Application Scenario

1. Cooling water circulation: For main and auxiliary engine cooling.
2. Seawater transportation: For cleaning or utility purposes.
3. Fresh water supply: Domestic and drinking water transport.
4. Fire-fighting system: Main pump for ship firefighting systems.

5. Performance Advantages

1. High efficiency: Single-stage design for low energy consumption and long-term continuous operation.
2. Low maintenance cost: Corrosion-resistant materials and simple design reduce maintenance frequency and cost.
3. Environmental adaptability: Compatible with fresh water, seawater, and mildly corrosive liquids.
4. Flexible installation: Vertical connection to pipelines requires no additional foundation support.

6. Maintenance and Care

1. Regularly check seals for leakage and replace worn parts promptly.
2. Clean impeller surfaces to remove salt or dirt buildup.
3. Monitor pump for smooth operation without abnormal vibration or noise.
4. Lubricate bearings regularly as per manual instructions.

7. Selection Guide

1. Flow and head requirements: Match pump model to actual usage needs.
2. Conveyed medium characteristics: Consider medium’s corrosiveness, temperature, and viscosity.
3. Ship’s electrical system: Ensure motor power and voltage compatibility.
4. Installation space: Choose a compact design for available ship space.
