SL Vertical pipeline fiberglass plastic centrifugal pump corosion resistance

A vertical, inline centrifugal pipeline pump engineered in modified phenolic glass-fiber reinforced plastic (FRP) for long-term corrosion resistance and reliable operation in aggressive chemical environments. This single-stage, single-suction vertical pump is designed for inline mounting in pipeline systems and delivers an energy-efficient solution for transferring corrosive liquids where metal pumps would suffer rapid deterioration.

Key features

• Corrosion-resistant construction: flow-wetted parts molded from modified phenolic FRP using high-temperature, high-pressure processing to resist acids and salts.
• Vertical inline design: single-stage, single-suction configuration saves floor space and simplifies piping; ideal for direct pipeline installation.
• Lightweight, high-strength structure: lower support requirements and reduced risk of deformation under operating loads.
• Energy efficient and reliable: steady operation with low power consumption and simple mechanical design for easy maintenance.
• Temperature and chemical tolerance: suitable for many non-oxidizing acids and corrosive solutions (see compatibility below).

Typical pumped liquids

• Concentrated hydrochloric acid
• Dilute sulfuric acid
• Non-oxidizing strong acids
• Organic acids and various inorganic salts

Suitable applications

• Chemical and petrochemical plants
• Pharmaceutical and pesticide production
• Chemical fiber and daily-chemical manufacturing
• Water and wastewater treatment
• Metal surface treatment and electroplating lines
• Environmental protection and corrosion-resistant process systems

Performance ranges (typical model family)

• Flow rate (Q): 3.2 to 100 m3/h
• Head (H): 12.5 to 32 m
• Motor power: 0.75 to 11 kW
• Nominal flange/caliber range: 25 mm to 100 mm

Model coding example

• SL40-20: “SL” = vertical FRP centrifugal pipeline pump; “40” = inlet/outlet diameter (mm); “20” = nominal pump head

Why choose this pump

Its combination of phenolic FRP wetted components and a vertical inline layout makes this pump especially cost-effective for corrosive-service duty where metal pumps would require frequent replacement or expensive linings. The pump offers lower installation footprint, simplified maintenance, and efficient hydraulic performance for continuous process service.
