Suction Line Connections
Super Products hose-to-hose and hose-to-tube
connections provide for fast set up of suction lines. This
is achieved by providing loose fitting male and female
ends of each length of suction hose or Supertube
aluminum suction tube. The loose fit allows for quick and
easy assembly. An O-ring gasket is placed over the male
coupler before assembly to female coupler to eliminate
air leaks. A lockring secures the ends together and
snaps overcenter.
This coupler system is used on all four (4), six (6) and
eight (8) inch diameter suction line systems. In
determining the best overall suction line set-up, the
following facts should be considered:
1. Larger hose diameters provide greater loading rates.
2. Loading rates are reduced as conveying distance is
increased.
3. Physical effort required relative to hose size:
a. Four (4) inch diameter hose and smaller can be
handled by one (1) man with minimal rest
periods.
b. Six (6) inch diameter hose can be handled by
one man but requires frequent rest periods.
Normally two (2) men will alternate or multiple
smaller hoses are used at work area.
c. Eight (8) inch diameter hose can not be handled
by the average man without great physical
exertion. Normally fed with shovels, wheel
barrows or multiple smaller hoses.
4. The chart below gives the recommended normal
particle size range for each hose diameter.
Occasional particles larger than those indicated
below can be handled.
Hose Diameter Particle Size
8" 3"
6" 2"
4" 1"
2.5" 0.5"
5. Bends reduce loading rates significantly. Straight
runs with a minimum number of long radius bends
made with smooth bore suction hose are the most
efficient.
Suction Line Set Up Guidelines
1. Install relief valve as shown in this manual.
2. Use largest diameter suction line possible.
Performance is affected by material handled, Mud
Dog™ model, and crew size. Use Supertube for
straight runs and hose for bends and material
pick-up.
3. When using Y connectors, branch from eight (8) or
six (6) inch diameter main suction line to multiple four
(4) inch hoses whenever possible. An average
person will achieve higher loading rates over the
period of a full shift using four (4) inch diameter
suction hoses.
a. Minimize length of all suction lines.
b. Minimize number of bends in all suction lines,
use of Supertube reduces excess bends.
c. Install permanent access ducting in area to be
cleaned frequently.
