Series DRH · Discharge Service
Sand Discharge Rubber Hose
High-pressure discharge hose for slurry, sand and gravel delivery lines.
Heartwork DRH sand discharge rubber hose delivers dredged material from the pump to the discharge point at 1.0–2.5 MPa. Choose steel-wire reinforcement (which also supports suction service) or fabric braid for lighter, cost-optimised runs, with burst pressure at 3× working pressure for site safety.
Key Features
Why field crews specify Heartwork
1.0 – 2.5 MPa
High working pressure with burst safety factor of 3× — engineered for main discharge lines.
Steel wire or braid
Steel-wire type also handles suction; fabric braid version optimises weight and cost.
Anti-aging cover
Black weather/ozone/seawater resistant rubber with orange spiral (solid black optional).
Fast connection
Flanged, non-flanged or steel sleeve ends with fixed, loose or quick-coupling options.
