Leading OEM choice for vacuum cleaning
systems
• Patented Tri-Lobe Design for quiet operation and
low pulsation
• Heavy-duty design for reduced downtime
• Advanced oil/air seals for reliable oil-free air
delivery
• Independent oil sumps prevent cross contamination and allow the vacuum pump to
operate safely on an incline when used in carpet
cleaning applications
• The inlet and outlet ports include both flange
and FNPT connections for ease of plumbing
• More than 5,000 units in active operation
to date
TriFlow: Setting the Industry Standard Quiet Operation
• Three lobe impeller geometry allows higher throughput while creating lower pulsation levels
than two lobe units, resulting in reduced noise
• An internal feedback porting arrangement contributes to the further reduction of noise
Quality Promise

All sales final. Optional extended warranty available.
Quality Construction
Each model incorporates the following for longer service life, reduced downtime and maintenance
• Highly reliable Dual Splash Lubrication
• Heavy duty bearings
• High strength timing gears
• Integral heat dissipation fins on the case to help maintain proper clearances
Built in oil level site windows.
OiL-Free air Delivery
• Piston ring seals are incorporated on each impeller shaft with a lip seal on the drive shaft, providing
superior sealing to prevent oil leakage into the air chamber
• Independent oil sumps prevent cross contamination and allow the vacuum pump to operate safely on an
incline when used in carpet cleaning applications
FLexible Installation
• Unique, integral mounting surfaces are precision machined for ease of installation and drive system
alignment
• Critical mounting dimensions are similar to those of existing two lobe positive displacement vacuum
pumps allowing for system upgrades
• The inlet and outlet ports include both flange and FNPT connections for ease of plumbing

A RHBD or Right Hand Bottom Discharge
TriFlow may also be used as a THRD or Top Hand Right Discharge. These are
the only 2 ways to configure a RHBD machine. The "hand" refers to where the drive shaft is.
We also stock the GYCLMCA0169 Left hand bottom discharge part number 46-030
