Important Safety Information
IMPORTANT Safety Information – MUST READ
DISCONNECT THE MAIN POWER SUPPLY AND
DISSIPATE ALL POTENTIALLY HAZARDOUS
ENERGY SOURCES PRIOR TO SERVICING OR
MAINTAINING EQUIPMENT
Belanger® recommends that all workers observe the OSHA (U.S. Department of
Labor Occupational Safety & Health Administration) Lockout / Tagout procedure
prior to performing service or maintenance on machinery and equipment.
Note: Reference the OSHA standard for the Control of Hazardous Energy (Lockout/Tagout), Title 29
Code of Federal Regulations (CFR) Part 1910.147 and the example provided in 1910.147
Appendix A for practices and procedures necessary to disable machinery or equipment, thereby
preventing the release of hazardous energy while employees perform servicing and maintenance
activities. The standard outlines measures for controlling hazardous energies – electrical,
mechanical, hydraulic, pneumatic, chemical, thermal, and other energy sources.
Note: Reference the OSHA standard 29 CFR 1910.331 to 29 CFR 1910.335 for safe work practices to
protect employees working on electrical circuits and equipment. This section requires workers to
use safe work practices, including lockout and tagging procedures. These provisions apply when
employees are exposed to electrical hazards while working on, near, or with conductors or systems
that use electrical energy.
Note: Both referenced OSHA standards can be found at the following website: http://www.osha.gov/law-
regs.html. Browse to the General Industry tab under the Find an OSHA Standard heading, scroll
down to the link of interest and click on it.
Doing so will prevent unexpected energization, startup, or release of hazardous
energy while maintenance and servicing activities are being performed.

Introduction
Belanger® has developed the DuraFlo™ Pumping Station product line. It is ideal for medium and high-pressure
applications. The DuraFlo™ product line provides an assortment of pumping platforms that can be used in multiple
applications. The DuraFlo™ product line is available in an 18 GPM pumping platform with either a 10 hp or 15 hp
motor, or a 36 GPM pumping platform with either a 15 hp or 25 hp motor. These pumping station options allow the
flexibility to supply a medium-volume water application that can deliver 600 to 1100 psi.
Built for longevity, the DuraFlo™ pumping platforms are assembled with high-quality components. All frames are
powder-coated for corrosion protection. The powertrain system connecting the motor and pump is a pulley system
comprised of cast sheaves and cogged V-style belts. ompared to standard V-belts, cogged belts run cooler, last
longer, and operate with a higher efficiency. Each pulley is locked to its respective shaft with a taper-lock bushing and
torqued according to the proper specification. The powertrain is also protected with a front and back plastic guard
which provides a safe operating environment during operation. Industrial duty motors are used on all four platforms.
The construction of these motors offers superior durability. Another benefit of the industrial duty motors is the pre-
lubricated, double-shielded oversized bearings to accommodate varying belt loads and tensions. The industrial duty
motor also provides a high-efficiency energy design. This design uses class “F” copper windings that allow the motor
to operate at higher temperatures than normal and still maintain durability. The DuraFlo™ product line has the
trademark “Green and Yellow” Dura product color combination (green frame/yellow tank), which allows customers to
easily associate these pumping stations with the durability known with Belanger® Dura components.
The 18 GPM pumping platforms include a Wanner™ H-25 Hydra- ell diaphragm pump that is capable of operating
fresh water or reclaim water. The main water inlet is sized no less than 1-inch ID pipe or hose. The main water feed
connects directly to a float valve assembly, which is easily adjusted, to maintain the proper water level in the holding
tank. The float valve used on this pumping platform has a 3/4” inlet. The pump is fed with a 2-inch suction hose from
the holding tank. A low-level mechanical switch assembled inside the tank also comes standard to prevent the pump
from running without water. A pressure relief (unloader) valve is attached to the pump by a 1/2-inch hydraulic hose
assembly, and also uses a 1/2-inch hydraulic hose assembly to unload water back into the holding tank. When the
nozzle is set to the proper pressure, the valve will unload approximately 2 GPM. The distribution manifold, located
near the pump, supports a 1-inch MJI fitting and connects to a single feed spray application.

2) Install the outlet plumbing from the outlet port of the Distribution Manifold to the desired piece of
equipment. See the image below.
Note: The outlet feed should be flexible hose from the unloader valve to any hard piping, solenoid
or tees.
Hose MUST be rated for a minimum pressure of 1500 PSI. Remember that the plumbing has
direct bearing on pressure at the nozzle (massive pressure drops are common to an incorrectly
installed system).
3) Install 3 phase wiring in accordance with any and all local and national codes (direction is
reversible).
Use caution, this machine starts automatically. Avoid contact with high pressure spray, as
serious personal injury may occur.
