Product Description
The cast iron horizontal multistage pump is a horizontally installed centrifugal pump with a segmented design, consisting of an inlet section, intermediate stages, outlet section, and tie rods. Mainly used for conveying clean water without solid particles or liquids with similar physical/chemical properties. The cast iron small bore horizontal multistage pump is reliable. Compared to stainless steel, it has relatively lower cost. Primarily used for domestic air conditioning circulation and industrial liquid transfer, such as circulation and pressure boosting of demineralized water, soft water, purification systems, and light oil. Suitable for small air conditioning cycles, cooling systems, industrial cleaning, water treatment (water purification), aquaculture, fertilization/dosing systems, etc. This light-duty cast iron horizontal pump is cost-effective.
Product Features
Media Handling
Suitable for conveying clean water or weakly corrosive media; not suitable for strongly corrosive liquids.
Corrosion-Resistant Material
Wet-end parts (e.g., pump body, impeller, guide vanes) conventionally use cast iron material. The shaft seal uses hard alloy and fluororubber mechanical seals, allowing the pump to handle mildly corrosive media. The cast iron horizontal multistage pump is adaptable.
Lightweight Material
The pump body standard uses cast iron, relatively low cost, lightweight, easy to install and move.
Structural Design
The pump body is composed of multiple sections (section shells) connected in series along the axial direction,each containing one impeller stage, fixed by tie rods, compact structure and easy maintenance.
Operation Balance
Rotor components use high-quality materials, good dynamic/static balance performance, low vibration, low noise. The light-duty cast iron horizontal pump runs smoothly.
Material Flexibility
Inlet section material can be selected as cast iron or stainless steel based on medium characteristics. The cast iron small bore horizontal multistage pump offers options.

FAQ
Q: What is the main cost advantage of using cast iron?
A: The primary advantage of the cast iron horizontal multistage pump is its lower initial cost compared to stainless steel models, making it a budget-friendly option for applications where corrosion resistance is not the primary concern, such as closed-loop clean water systems.
Q: Can the inlet section be made of stainless steel if needed?
A: Yes, the light-duty cast iron horizontal pump offers material flexibility; the inlet section can be ordered in stainless steel to handle mildly corrosive media or for compatibility reasons, while keeping other parts cast iron for cost efficiency.
Q: Is this pump suitable for light chemical dosing systems?
A: With its capability to handle weakly corrosive media and appropriate seal materials, the cast iron small bore horizontal multistage pump can be used in light chemical dosing or metering systems, but compatibility with the specific chemical should be verified.
