CF Series Horizontal Replaceable Membrane Expansion Tanks (Carbon Steel) — 19L to 100L

Lead Pump's CF Series Horizontal Replaceable Membrane Expansion Tanks (Carbon Steel) — 19L to 100L is a professional-grade horizontal expansion tank line designed for water supply, heating, and irrigation systems where vertical headroom is limited. Manufactured in our state-of-the-art 20,000m² facility with 200+ skilled workers, each CF tank features a robust carbon steel shell with anti-corrosion coating and a fully replaceable rubber bladder (available in butyl or EPDM). The horizontal form factor allows installation in crawl spaces, under sinks, or inside equipment cabinets — making it the preferred choice for compact booster sets and space-constrained mechanical rooms. The series covers 7 models from 19L to 100L, with common 1" threaded connection and pre-charge of 1.8-2.0 bar. All units are 100% pressure-tested before shipping, backed by CE, NSF61, and ISO9001 certifications. Factory-direct supply, OEM branding, and custom packaging available. Trusted by pump manufacturers and system integrators across Europe, the Americas, and Southeast Asia.

Installation Best Practices of CF Series Horizontal Replaceable Membrane Expansion Tanks (Carbon Steel) — 19L to 100L:

1.Mount the tank horizontally using the provided wall bracket (models 19L-24L) or place on a flat, level surface (36L-100L)

2.Pre-charge to 1.8-2.0 bar before connecting to system (adjust to 0.2 bar below pump cut-in pressure)

3.Use flexible hose connectors to avoid transmitting vibration to rigid piping

4.Install a shut-off valve between tank and system for easy maintenance

5.Check pre-charge pressure annually — recharge if drop > 0.3 bar
