PUMP DESCRIPTION
Eco-Seal pumps are based on our industry leading Signature Series of pumps but with one major dierence: the pumps are
engineered with a high performance lip sealing system for enhanced leak protecon. The result: an aordable, long lasng,
low maintenance bushing-design pump which meets more stringent environmental and safety standards.
There are three lines of Eco-Seal Series pumps: 300 Eco-Seal – the standard pump; 300 Eco-Seal S – short drive neck for ac-
cess in ght spaces; 300 Eco-Seal ED – extended duty.

PRE-INSTALLATION CLEANING
Any large foreign maer that enters the pump WILL cause extensive damage. The supply tank and piping
MUST be cleaned and ushed before pump installaon and operaon.
LOCATION AND PIPING
1. Locate the pump as close to the source of supply as possible to maximize intake.
2. Piping MUST have proper support to prevent any load being placed on the pump.
3. Piping and ngs MUST be at least the same diameter as the pump port.
4. Minimize the number of intake line ngs and piping turns or bends to maximize performance.
5. Install a strainer or screen on the sucon line to prevent large foreign maer from entering the
pump. Place the strainer in an accessible locaon for frequent cleaning.
6. It is recommended to install a suitable device to prevent over-pressurizaon of the system.
Bowie Pumps of Canada Ltd. supplies a bi-direconal pressure relief plate (BP7000) for this
purpose.
7. Sucon and discharge lines and piping MUST be free of all leaks.
NOTICE:
Bowie pumps must be installed only in
systems design by qualied engineering
personnel. Bowie pumps should only be
installed in dues for which Bowie Pumps
of Canada Ltd. have specied the aributes
of the pump. System design must conform
to all applicable regulaons and codes and
provide warning of all system hazards.
NOTICE:
PTO and hydraulically driven units MUST
use speed control devices to limit the sha
from exceeding maximum RPM specica-
ons, regardless of unloading speeds. If
uid ow is less than expected, consult the
“General Pump Troubleshoong” secon.
INSTALLATION
Operaon without guards in
place can cause serious per-
sonal injury, property damage,
or death.
TRUCK MOUNTING
Bowie pumps are designed to be installed in a horizontal posion with base plates mounted and parallel
to ground on a at surface. The pump should be installed with access to both the drain plugs and mul-
ple grease ngs on the pump. The pump may be bolted to the truck frame or on a saddle hung below
the frame, however it MUST be grouted and bolted, ensuring rm xing and a reducon in noise and
vibraon.

ES IOM Rev 1 - 5/13/2021 4
HYDRAULIC DRIVE
Bowie pumps may be hydraulically driven. The hydraulic motor should be well supported with the drive
sha in-line with the pump sha in all respects. A sleeve joint is recommended to compensate for any
play caused by road condions. Bowie Pumps of Canada provides a Hydraulic Mount Adapter for this
purpose. Please contact your nearest Bowie agent for more informaon.
General guidelines for proper pump drive:
1. The sha of the hydraulic motor should be aligned with the Bowie pump drive sha. The two
shas should be parallel and concentric.
2. Alignment of the hydraulic motor sha and the Bowie pump drive sha can be measured using a
straight edge and feeler gauges, or a taper gauge or caliper.
3. Axial misalignment (in which the shas are parallel but are not concentric) is measured at the
coupling. The maximum allowable axial misalignment is 0.005”.
4. Angular misalignment (in which the shas are concentric but are not parallel) is measured at the
coupling. The maximum allowable angular misalignment is 20°.
Failure to follow these guidelines may result in excessive wear on the internal components of the pump.
This will result in improper performance and may result in premature pump failure. Failure to follow
these guidelines may also result in uneven turning of the gears, in turn causing a surging vibraon to the
uid system.
POWER TAKE OFF (PTO) DRIVE
Bowie pumps may be driven by a PTO drive. A direct drive sha with a universal joint on each end of the
sha is used to connect the pump to the drive. A sleeve joint can be used to compensate for any play
caused by road condions.
General guidelines for proper pump drive:
1. The angle of drive sha between pump and PTO must be NO LESS than 3° and NO GREATER than
20° to ensure proper performance and protect from premature pump failure.
2. Use the least number of jackshas as is praccal.
3. Use an even number of universal joints (U-joints).
4. The yokes of the universals at both ends of the jacksha must be in phase and parallel.
5. The angle between the jacksha and the pump sha must be NO LESS than 3° and NO GREATER
that 20° (refer to guideline 1).
6. The PTO sha must be balanced and maintained to manufacturers specicaons.
7. The PTO sha RPM must not exceed the recommended pump RPM for operaon.
Failure to follow these guidelines may result in excessive wear on the U-joints, bearing, seals and internal
components of the pump. This will result in improper performance and may result in premature pump
failure. Failure to follow these guidelines may also result in uneven turning of the gears, in turn causing a
surging vibraon to the uid system.
NOTICE:
Drive shaft angular and axial alignment can
be determined using a straight edge and
feeler gauges.
INSTALLATION
Operaon without guards in
place can cause serious per-
sonal injury, property damage,
or death.

ES IOM Rev 1 - 5/13/2021 5
PRE-START UP CHECK LIST
1. Check alignment and connecons of all piping/tubing to the pump. Pipes must be supported
to prevent drop down or pressurized recoil when the pump anges or unions are disconnected.
2. Inspect complete piping/tubing system ensuring that no external piping loads are being placed
on the pump.
3. Secure appropriate hose connecons.
4. Check all nuts and bolts, anges, and base mounng xtures for ghtness.
NOTICE:
If dicules or issues are experienced dur-
ing start up, please consult the “General
Pump Troubleshoong” secon.
NOTICE:
“Dry running” the pump WILL result in gear
and pump damage.
START UP PROCEDURES
1. Ensure appropriate valves are open in the inlet and discharge lines.
2. Start the pump. Priming should occur within one minute.
3. Inspect all associated piping, ngs and system equipment for issues such as leaks, noise, vibraon
and overheang.
4. Check ow rate to ensure the pump is operang within expected limits.
5. If equipped, check the relief valve pressure seng by momentarily closing a valve in the discharge
line and reading the pressure gauge. This pressure must be a minimum of 20-30 psi (1.4-2.1 Bar)
higher than the maximum system operang pressure or pressure relief plate seng, and must not
exceed 150 psi. DO NOT operate the pump against a closed discharge valve for more than 15
seconds. If adjustments need to be made, refer to the “Relief Valve Seng and Adjustment” sec-
on of this manual.
NOTICE:
The range of temperatures that pump sur-
faces will develop is dependent upon fac-
tors such as product temperature and am-
bient temperature of operaon. There
may be instances where the external pump
surface can exceed 50°C. In these situa-
ons, proper warnings/guards MUST be
used.
PUMP OPERATION
Pumps operang against a
closed valve can cause system
failure resulng in personal
injury and property damage
Pumping hazardous or toxic
uids can cause personal injury
and property damage.
NOTICE:
High Viscosity uids and / or low uid lev-
els will lead to high sucon at start up.
This will cause a “dry run” situaon. The
pump must be adequately primed by add-
ing uid to the inner pump area through
drain plug openings in the back plate.
Disconnecng uid or pressure
containment components dur-
ing pump operaon can cause
serious personal injury, death
or major property damage.

ES IOM Rev 1 - 5/13/2021 6
NOTICE:
Only lubricang, non-corrosive uids may
be le in the pump for an extended period
of me. Any other uids must be ushed
from the pump immediately.
NOTICE:
Aer ushing the pump some residual uid
will remain in the pump and piping.
FLUSHING THE PUMP
1. Evacuate as much exisng uid as possible from the pump.
2. Run cleaning uid through the pump intake. The cleaning uid should be compable with the
pump O-rings and gear material. In situaons with “scky” uids that solidify within the pump (i.e.
waxes, adhesives etc.) use a uid that prevents solidicaon of the uid to facilitate ushing.
NOTICE:
Properly dispose of all waste uids in ac-
cordance with appropriate codes and regu-
laons.

marker will void all warranty of BPOC
products.
BI-DIRECTIONAL PRESSURE RELIEF PLATE SETTING
The Bi-Direconal Pressure Relief Plate pressure seng should be set a minimum of 20-30 psi higher than
the operang pressure. When adjusng the pressure seng, the correct locking cap must be adjusted for
the correct direcon of ow at operang rotaonal speed of the pump’s drive sha. Pressure may be ad-
justed within a range of approximately 20 psi per spring. Addional springs are available for higher psi
changes. Contact your BPOC repair or warranty agent for more informaon.
Adjusng the PRESSURE SETTING:
1. To INCREASE the pressure seng, remove the correct locking cap (see selecng the correct locking
cap). Loosen the locking nut, and then rotate the seng screw clockwise. Record the dierence
between original and new sengs. Tighten the locking nut, and replace the locking cap.
2. To DECREASE the pressure seng, remove the correct locking cap (see selecng the correct lock-
ing cap). Loosen the locking nut, and then rotate the seng screw counterclockwise. Record the
dierence between original and new sengs. Tighten the locking nut, and replace the locking cap.
Selecng the CORRECT LOCKING CAP viewing the front plate of the pump:
To adjust ow pressure for CLOCKWISE sha rotaon:
a) The drive sha below the idler sha. Adjustments must be made to the RIGHT side spring.
b) The drive sha above the idler sha. Adjustments must be made to the LEFT side spring.
To adjust ow pressure for COUNTERCLOCKWISE sha rotaon:
a) The drive sha below the idler sha. Adjustments must be made to the LEFT side spring.
b) The drive sha above the idler sha. Adjustments must be made to the RIGHT side spring.
NOTICE:
Adjustment of pressure sengs by any
party other than a specied BPOC repair or
warranty agent will void all warranty of
BPOC products.
NOTICE:
Any internal pump relief valve is designed to protect the pump from excessive pressure and
must NOT be used as a system pressure control valve. See your local Bowie dealer for a list
of Bowie manufactured system pressure control valves.
BI-DIRECTIONAL PRESSURE RELIEF PLATE
An available bi-direconal pressure relief plate is manufactured and can be supplied by Bowie Pumps of
Canada Ltd. This will set a dierent maximum pressure for each direcon of uid ow. Inial pressure is
set at the factory to the customer’s specicaons, based on the specic operaonal rotaonal speed of the

LUBRICATION
Bowie’s Eco-Seal™ pumps are designed with a system of high-performance elastomeric seals and a combi-
naon of cross-hatched Aluminum-Bronze bushings. These pumps contain ve (5) easily accessible grease
ngs which allow grease to lubricate the brass bushings. The pumps come fully lubricated with Metalon®
Hi-Tech EP 1.5 grease and are ready for use. This grease’s penetraon rang bridges the NLGI #1 and #2
grades. Once your pump is in operaon, it is absolutely crical that a regular lubricaon program be fol-
lowed to allow the pump to operate as designed and to prevent premature failure.
We recommend the following lubricaon ‘Best Pracces’:
• Lubricant: Select grease with the following properes: water resistance, rust and corrosion protec-
on, extreme pressure protecon and lm strength and stability through temperatures ranging
from -40°C/F to 300°C/570°F.
• Quanty and Time for Normal Operang Condions: Bowie recommends 2-4 ounces of grease
applied approximately every four (4) operang hours in the front drive neck of the pump. For all
other grease ng locaons, we recommend 1-2 ounces of grease applied every four (4) operang
hours. The actual amount of grease to be applied can be idened as the point when high re-
sistance to further greasing has been achieved. For operang condions above those specied
refer to the above noce.
Normal operang condions for greasing pracces are:
• Operang Temperature ≤ 90° C (Progressive Helical Steel Gears) or ≤ 50° C (Buna-N rubber Gears)
• Rotaon Speed ≤ 500 RPM
• Discharge Pressure ≤ 70 PSI
NOTICE:
Strainers must be cleaned regularly to
avoid pump starvaon. Schedule is de-
pendent upon the applicaon and
condions.
PREVENTATIVE MAINTENANCE
NOTICE:
For operang condions ABOVE NORMAL, Bowie recommends 2-4 ounces of grease ap-
plied approximately every two (2) operang hours in the front drive neck of the pump. For
all other grease ng locaons, we recommend 1-2 ounces of grease applied every two (2)
operang hours. The actual amount of grease to be applied can be idened as the point
when high resistance to further greasing has been achieved.
Failure to set vehicle emergency
