Dual Main Pump & Auxiliary Multi-Pump System

The host unit continuously monitors the pressure in the pipe network and communicates it to the auxiliary pumps. It automatically controls the operation and PID settings of each auxiliary pump based on real-time pressure conditions.

The system monitors the status of all pumps. If the host pump fails, the standby host automatically takes over. If an auxiliary pump fails, it is bypassed, and the next auxiliary pump is started. This ensures seamless automatic switching between main and auxiliary pumps.

Main and auxiliary pumps can operate alternately at scheduled intervals, balancing workload across the system to extend pump life.

This industry-leading setup supports dual main pumps and multiple auxiliary pumps, ensuring reliable operation even if one main pump is offline, while optimizing performance and energy efficiency.

Types of Water Pumps (Industrial & International Trade Focus)

Below is a structured list of water pump types, categorized by core working principles, structural designs, conveyed media, and application scenarios. It includes key features, typical use cases, and renowned international brands to support selection and trade-related communications.

I. Classified by Core Working Principle (Most Common)

Pump Type

Working Principle

Key Features

Typical Application Scenarios

International Brand References

Centrifugal Pump

Relies on high-speed impeller rotation to generate centrifugal force, propelling media to the outlet (kinetic energy → pressure energy).

Large flow rate, wide head range (low → high), simple structure, easy maintenance; accounts for over 80% of industrial applications.

Industrial circulating water, water supply/drainage, HVAC, agricultural irrigation, petrochemical transportation.

Grundfos, KSB, Wilo, Xylem

Positive Displacement Pump

Relies on changes in cavity volume to suck and discharge media (e.g., piston, gear, or screw extrusion).

High head, stable flow rate (unaffected by pipeline resistance), suitable for high-viscosity media.

High-pressure cleaning, hydraulic systems, crude oil/asphalt transportation, food processing (no shear requirements).

Bosch Rexroth, Netzsch, Eaton, Lewa

Special Principle Pumps

Non-traditional mechanical transmission (e.g., electromagnetic force, ultrasonic waves, jet negative pressure).

No mechanical wear, low noise, suitable for special media (corrosive, high-purity).

Laboratories, medical equipment, electronic semiconductor cleaning, small-scale pure water transfer.

Olympus, Pfeiffer Vacuum

Subtypes of Positive Displacement Pumps (Industrial-Grade)

  • Gear Pump: Compact structure; suitable for low-viscosity media (lubricating oil, diesel) in automotive and mechanical hydraulic systems.

  • Screw Pump: Single/double screw design; conveys high-viscosity media with particles (sludge, food slurry).

  • Piston/Plunger Pump: High pressure (up to several hundred bar), high precision; used in hydraulic systems, high-pressure cleaning, and oilfield water injection.

  • Diaphragm Pump: Shaft seal-free design, leak-proof; suitable for corrosive media (acids, alkalis) and solid-containing media (chemical industry, sewage treatment).
