Do not lean or step on them or use as climbing aid
–
Do not use them to support boards, ramps or beams
–
Do not use them as a fixing point for winches or
supports
–

pump.
2.3
Specific hazards
2.3.1
Hazardous pumped liquids
Follow the statutory safety regulations when handling
hazardous pumped liquids (e.g. hot, flammable, poisonous
or potentially harmful). Use appropriate personal protective
equipment when carrying out any work on the pump.
2.3.2
Lubricants
Ensure that the lubricant and pumped liquid are compatible
with each other. This is a precautionary measure in case of
accidental hose burst whereby the pumped liquid comes in
contact with the lubricant
(Refer datasheet for lubricant to
ensure compatibility)
2.3.3
Sharp edges
Pump parts, such as the shims, can be sharp
–
Use protective gloves when carrying out any work on
the pump

Layout and function
Peristaltic hose pump, Verderflex Dura, is simple by
design in its construction and operation. The medium
to be pumped does not come into contact with any
moving parts and is totally contained within a robust,
heavy-duty hose, which usually consists of an inner
layer, two – six reinforcement layers and an outer
layer. A rotor passes along the length of the hose,
compressing it. This motion forces the contents of the
hose directly in front of the rotor to move forward along
the length of the hose in a ‘positive displacement’,
peristaltic movement. In the wake of the rotor’s
compressing action, the natural elasticity of the
polymer reinforced rubber forces the hose to open and
regain its round profile, creating suction pressure,
which recharges the pump.
3.1
Design details
Verderflex Dura is a twin lobe, single rotor, peristaltic
pump with quick-fit tapered port flange design which
clamps and seals in one easy movement to speed
hose replacement.
