OVERVIEW
General Blower Operation
The NVE BLOWERS are severe duty vacuum pumps, designed to be used in
liquid waste pumping systems where extended operaon is desired. The
pump incorporates a ballast air cooling system to provide superior cooling,
allowing for extended operaon.
The air enters the intake under vacuum or at atmospheric pressure. As the
rotors rotate, a xed volume of air is moved along the wall of the cylinder
towards the exhaust where the pressure and temperature of the volume of
air increases. If the intake air is below atmospheric pressure, cooling air will
be drawn in when the rotor p passes the ballast port.
The airow capacity of the machine (in ACFM) is nearly proporonal to the
speed of the machine and is nearly constant with changes in inlet or outlet
pressures.

General Blower Construction
Location of Serial Number
Each blower should have a brass colored tag with an embossed serial num-
ber. In addion, the serial number and blower direcon as assembled at the
factory are stamped into the top of the housing as shown:

SPECIFICATIONS
Operating Environment
The 5314 blower is designed to move atmospheric air. Do not use to move
explosive or corrosive gasses or operate the blower in an area with explosive
gases. Any materials in the intake air must be ltered and separated from
the air by means of an intake lter, moisture trap and/or a cyclonic lter.
The ballast inlet must be posioned and protected from ingesng debris,
uid or explosive gases.
Operating Limits
The blower must be operated within all limits at all mes. This typically
means the blower performance is limited by the exhaust temperature and
temperature rise over ambient for the blower.

Air Flow Control
The airow rate on the blower can be adjusted by changing the speed of the
blower. This can be accomplished by changing the PTO rao, gearbox rao,
belt drive pulley diameters or engine speed.
Noise Level
The noise level of the blower increases signicantly with higher levels of
vacuum and RPM. To minimize noise, operate the blower at the minimum
speed and vacuum level to achieve the desired performance results.
It is recommended the operator monitor the blower while running and listen
for resonances (increased levels of noise) that may occur at certain RPM’s
and operate the blower at speeds above or below the resonance speeds to
reduce excess noise.

Diesel Engine Precautions
· DO NOT OPERATE BLOWER WITH A DIESEL ENGINE RUNNING
AT LOW RPM’S AS TORQUE PULSES CAN CAUSE ROTOR LOBE
CONTACT AND DAMAGE TO THE BLOWER.
When directly driving the blower with Diesel engine, bring the engine up to
operang RPM and then engage the blower via the clutch. Be sure to start
the blower under no load condions.
Use cauon when using a Diesel engine that is signicantly oversized for the
operang point of the blower. Doing so can result in an ineral mismatch,
excess torsional vibraons at low RPM’s and blower lobe contact.
For more informaon Diesel torsional vibraons, see the technical report by
LoveJoy tled New Twists to Diesel Vibraon at www.lovejoy-inc.com .

· DO NOT USE A HAMMER TO SLIDE THE COUPLERS ONTO
THE SHAFT AS THIS MAY RESULT IN BLOWER DAMAGE
LoveJoy Coupler - Please see the LoveJoy website www.lovejoy-inc.com for
details on the alignment.
· Failure to properly align the couplers can cause premature
wear of the blower bearings and coupler sleeve.
· Couplers must be guarded to prevent entanglement.
BELT DRIVE
We do not recommend the use of cogged, synchronous or ming belts.
The driving pulley from the prime mover must be mounted on the intake
side of the blower to prevent unloading of the blower bearings.
Use a narrow hub sheave and insure that the inner hub face is not more than
1/4” from the face of the gearbox. Be sure to also use an adjustable belt
tensioning system to allow compensaon for belt wear.
· Excessive belt tension could damage the blower and prime
mover.
· Belts and pulleys must be guarded to prevent entanglement.
Use matched sets of V-belts to insure uniform torque transmission. If a belt
goes out, replace the whole set.
DRIVE SHAFT
U-Joint operang angles at each end of the sha should always be at least 1°
to prevent yoke bearing failure, but do not exceed the manufacturers maxi-
mum recommended angles for the operang RPM.
U-Joint operang angles on each end of a drive sha should always be equal
within 1° of each other to cancel an angle vibraon.

· Use a drive sha loop to catch sha in the event of failure.
· It is suggested that overload protecon be used on the blower
driveline.
HYDRAULIC DRIVE
The blower can be driven with an appropriately sized hydraulic system uliz-
ing a hydraulic motor with an SAE C, 4-bolt or 2-bolt ange by purchasing a
hydraulic mount (purchased separately) and appropriate couplers.
PTO Drive
PTO’s must be properly sized to drive the blower. For more informaon on
driving blowers with PTO’s, please see the Chelsea Blower Torque Guide Bul-
len HY25-0075-B1-US available at www.parker.com .
· Improper use of “Hot Shi” (i.e. clutch type, constant mesh)
PTO’s can result in severe damage to the blower driveline and
blower. Take extra precauons to operate PTO’s within the
manufacturer’s recommendaons
PLUMBING AND PIPING
Do not hang plumbing from blower anges. Use isolang anges or isolat-
ing hose to couple blower to piping to prevent dead weight from hanging
o blower and to allow for thermal expansion. Failure to do so may result in
rotor contact with housing. Use only clean piping insuring it is free of dirt,
scale, cungs, weld spaer, and foreign materials of any kind.
The intake and exhaust system can be plumbed with 6” hose. The ballast
system should be plumbed using 6” hose minimum. Be sure to locate the
ballast inlet away from heat, debris and uid sources as exposure to these
may result in damage to the blower.

RECOMMENDED ACCESSORIES
Exhaust Silencer
Posive displacement blowers are inherently noisy due to their design. NVE
oers compable silencers for the exhaust to reduce decibel levels in the
operang environment.
If using a non-OEM silencer, it should be tested for eecveness by blanking
o the inlet and monitoring exhaust gas temperature with the blower run-
ning for at least one hour. The blower should not exceed specied exhaust
gas temperatures.
Inlet Filter
The intake lters are designed to ensure maximum airow eciency why
keeping out unwanted debris. The lters supplied by NVE use a stainless
steel screen and can be cleaned.
Four Way Valve and Hoses
If it is intended to operate the blower in the pressure mode, a four way valve
will be required. The 4-way valve size should match the hose size used in the
applicaon.
Pressure Relief Valve
If the blower is intended to be used in pressure mode then a pressure relief
valve is required. NVE recommends the use of Kunkle pressure relief valves
as they have been proven to work well and have sucient ow capacity. The
valves we supply are factory set to 10 PSI and are sealed. We do not recom-
mend the blower to be operated over 10 PSI nor do we recommend the use
of imported relief valves.
Vacuum Relief Valve
Vacuum relief valves are not typically needed with NVE blowers. If the ap-
