Flamco

Blending top-up pressurisation with on-demand chemical dosing, the Flamco PressDS 225D Twin Pump maintains stable pressure on sealed systems while automatically mixing inhibitor from a dedicated tank at a preset ratio.

This floor-standing unit features a 4 Ltrs mains-fed break tank and an 18 Ltrs additive reservoir. Each top-up delivers water and the correct fluid blend together, cutting site visits and maximising system protection. Ideal for commercial and industrial plant (guide volume up to 300,000 Ltrs).

• Dual pump duty/standby configuration
• Mix control user-set from 150%
• Top-up to < 18 L/min; max delivery 3 Bar
• Category 5 (Type AB weir overflow) protection

Integration is simple via MODBUS RTU, password-protected menus and volt-free contacts, with flood protection, service reminders and additive-empty alerts built in. Finished in black (RAL 9005).

Purpose-built for EN 12828 heating and chilled-water systems, this multifunction sealed-system unit combines automatic expansion control, pressurisation, deaeration and make-up in a single package.

A pressure-step degassing process—using a controlled pressure drop and patented PALL-ring media—removes dissolved gases even at equilibrium. A replaceable butyl bladder stores the expansion fluid at atmospheric pressure. Supplied with Flexvent Super, height-adjustable feet and a weight-capacity sensor.

• All-in-one functionality — expansion, pressurisation, deaeration and make-up
• Pressure-step deaeration with PALL-ring technology
• Replaceable butyl bladder — easy maintenance and long service life
• Delivered complete — Flexvent Super, adjustable feet, weight-capacity sensor

Designed for commercial, industrial and residential sealed LPHW/CHW installations requiring efficient air removal and stable operating pressures.
