Inline Circulation Pumps

Inline circulation pumps are designed for HVAC, chilled-water, heating, cooling-water, building water supply and industrial circulation systems. ZLZB® supplies horizontal and vertical centrifugal pumps, stainless steel inline pumps, canned motor pumps and cooling tower circulation pumps for different flow, head and installation requirements. Available models include ISW, IHW, ISG, IHG, TD and SPG series, widely used in commercial buildings, water treatment equipment, cooling towers, industrial water transfer and continuous circulation systems. Pump selection can be based on required flow, head, liquid temperature, pipeline size, installation space and operating conditions for reliable system performance.

Horizontal Centrifugal Pump for Water Supply and Circulation

• Designed for commercial water supply, cooling-water circulation, industrial water transfer and pressure boosting.
• Horizontal close-coupled construction provides compact installation and convenient access for maintenance.

Flow: 2.5-1200 m³/h | Head: 10-180 m

Stainless Steel Horizontal Pump for Industrial Liquid Handling

• Designed for water treatment, industrial circulation and selected liquid-transfer applications requiring stainless steel construction.
• Horizontal close-coupled design provides compact installation for commercial and industrial systems.

Flow: 1.5-1200 m³/h | Head: 8-150 m

Vertical Inline Centrifugal Pump for HVAC and Water Supply

• Designed for HVAC circulation, building water supply, cooling-water systems and pressure boosting.
• Vertical inline construction allows direct pipeline installation while reducing required floor space.

Flow: 8.2-1500 m³/h | Head: 7-158 m

Stainless Steel Vertical Inline Centrifugal Pump

• Stainless steel inline pump for water treatment, industrial circulation and selected corrosion-resistant liquid applications.
• Compact vertical construction supports direct installation in pipelines where space and material compatibility are important.

Flow: 8.2-1500 m³/h | Head: 7-158 m

Inline Circulation Pump for Heating and Cooling Systems

• Designed for HVAC circulation, chilled-water systems, heating systems and commercial building services.
• Inline suction and discharge connections simplify pipeline installation and reduce installation space.

Flow: 8-630 m³/h | Head: 9-81 m

SPG vertical canned motor inline pump for water circulation

F. SPG Vertical Canned Motor Inline Pump

Vertical Canned Motor Inline Pump for Water Circulation

• Designed for pipeline circulation, HVAC systems, heating and cooling applications and commercial water systems.
• Vertical canned motor construction provides a compact arrangement for installations with limited floor space.

Flow: 4-720 m³/h | Head: 10-50 m
