Water Retained (with drain feature): 80 ml after 5 minutes. Maximum Working Pressure: 16 Bar. Temperature Range: -10°C to +70°C. Exceeds flow requirements: Min flow 2000 l/min @1.7 Bar (Kv=92): specified in BSEN14339 Actual flow 4500 l/min @1.7 Bar (Kv=221) Insulation essential for temperatures of 0°C and below.

The Series 29/93 is the dimensional equivalent of a squat hydrant but with a full, straight bore from inlet to outlet. This allows a greatly enhanced flow-rate and ease of introduction and retrieval of pipe maintenance and measurement equipment. It is suitable for use with water and neutral liquids to a maximum temperature of +70°C. Complies with requirements of BS 750:2006 and BS EN1074-2:2004 and EN 14339:2005, underground hydrants. Also to BS EN 1074-6 for potable (drinking) water. Resistant to corrosion of other component parts. Resistant to disinfected products.
