CAUTIONS–READ FIRST!

WARNING: In any positive-displacement pump system,

a reliable pressure-protection device must be used in the

discharge piping to avoid a dangerous pressure increase, which

could cause the pump or any component in the discharge piping

to burst and can lead to serious injury. A pump-mounted integral

relief valve is not intended to be used in this manner.

WARNING: This pump contains powerful permanent magnets

that can cause serious injury. Read the appropriate section of

this IOM before doing any service work.

WARNING: Magnetic ﬁeld can disrupt medical implants such

as pacemakers. Implant wearers should remain a minimum of 0.3

m (1 ft) away from pump and 1 m (3 ft) away from disassembled

magnets.

WARNING: Magnets inside the pump can damage electronic

equipment or magnetic media.

WARNING: This pump is designed to rotate only in the direction

indicated. Do not run the pump in the opposite direction for long

periods because internal passageways that control axial thrust

will not work correctly, causing premature wear and reduced

pumping efﬁciency.

WARNING: The inner magnets on the back of the rotor

assembly are strongly attracted to the outer magnets in the

outer-drive assembly. During the separation process, there

will be a strong force of up to 136 kg (300 lbs) trying to pull

them back together, which can create a powerful pinch point.

WARNING: Failure to have each magnet segment in opposite

polarity with adjacent magnets will cause a signiﬁcant reduction

of coupling torque.

WARNING: Maximum temperature limits are based upon

mechanical stress only. Certain chemicals will signiﬁcantly

reduce maximum safe operating temperatures. Consult

Chemical Resistance Guide for chemical compatibility and

temperature limits.

WARNING: Prevent static sparking. If static sparking occurs,

ﬁre or explosion could result. Pump, valves and containers

must be grounded to a proper grounding point when handling

ﬂammable ﬂuids and whenever discharge of static electricity is

a hazard.

WARNING: For applications requiring CE or ATEX, refer to the

E Series Safety Supplement for addition cautions and warnings.

CAUTION: Only personnel who are familiar with the operation

and repair of mechanical products should perform the necessary

maintenance. You must familiarize yourself with the entire

contents of this manual prior to operating and/or performing any

maintenance.

CAUTION: When selecting a E Series pump for an application,

you must ﬁrst ensure that the pump components are compatible

with the process media.

CAUTION: Do not operate this pump in excess of its rated

capacity, pressure, speed and temperature.

CAUTION: Before any maintenance and repair is attempted,

disconnect the drive.

CAUTION: Before any maintenance or repair is attempted, bleed

all pressure from the pump through the suction or discharge lines.

CAUTION: Do not remove any pressure-containing components

during pump operation.

CAUTION: All E Series pumps contain residual hydraulic oil

from the factory production test. Hypar-FG 15 food-grade oil is

the standard production test ﬂuid, but any certiﬁed performance

testing may be done on a non-food grade oil, such as Unilube 32

(ISO 32) or Unilube 100 (ISO 100). Determine if this is compatible

with the ﬂuid you are pumping. If the ﬂuid is incompatible, then

the pump must be fully ﬂushed prior to use.

CAUTION: When pumping ﬂuids at elevated temperatures,

care should be taken to gradually increase temperature. Rapid

temperature increase can damage internal components.

CAUTION: Ensure that the pump has cooled to a safe

temperature before any maintenance or repair is attemped.

CAUTION: When pumping ﬂuids at elevated temperatures

the piping may expand, resulting in excessive stress on the

pump. This can cause pump failure. Care must be taken when

considering pipe design to avoid damage from thermal expansion.

CAUTION: All inlet and discharge plumbing should be clean and

free from foreign material prior to startup of pump.

CAUTION: When connecting to an electric motor, follow all

safety recommendations provided by the motor manufacturer.

CAUTION: Never remove safety guards from shafts, couplings,

V-belts or pulleys during operation. Doing so could result in injury.

CAUTION: Do not wear loose or dangling clothing or jewelry

near the equipment. These items could become caught in the

equipment and cause injury.

CAUTION: Before any maintenance or repair is attemped,

ensure that the pump has been thoroughly ﬂushed of any

hazardous ﬂuids. Review the Material Safety Data Sheet (MSDS)

applicable to the ﬂuid for proper handling.

• Crane, hoist or other suitable lifting device capable of

lifting at least 182 kg (400 lbs)

• Sturdy workbench that is positioned beneath the

lifting device and is ﬁrmly anchored to the ﬂoor, or if

unanchored, the workbench must weigh at least 182 kg

(400 lbs), and be strong enough to resist a lifting force of

up to 182 kg (400 lbs)

• Pump Disassembly Tool F-00096 or F-00097

The shaded area indicates the liquid as it

is drawn into the liquid inlet port of the

pump. As the rotor turns, atmospheric

pressure forces the liquid between the

rotor teeth and idler teeth. The two

arrows indicate the rotational direction

of the pump.

As the rotor continues to turn, the liquid

is forced through the crescent-shaped

area of the wetted path. The crescent-

shaped area divides the liquid and acts as

a barrier between the inlet and discharge

ports.

As the rotor continues to turn, the liquid

is forced past the crescent-shaped area

and moves toward the discharge port.

As the rotor completes one complete

rotation, the rotor and idler teeth

interlock, forcing the liquid through the

discharge of the pump. The pump may

take several rotations to completely

prime depending on the conditions of the

application.

The E SERIES GEAR PUMP is a rotating positive displacement pump. These drawings show the ﬂow pattern through

the pump upon its initial rotation. It is assumed that the pump has no ﬂuid in it prior to its initial rotation.

RELIEF VALVE PERFORMANCE

Optional integral relief valves provide pump protection

from over-pressure conditions. While not intended for

continuous use, internal relief valves protect the pump

from closed discharge valves or other intermittent

over-pressurization of the system.

Depending on the size of the pump, you will get one

of two relief valve designs, a non-externally adjustable

or an externally adjustable relief valve.The design

of the E1-2 thru E1-82 are spring-loaded and contain

only three parts.This design addresses the problem of

over-pressurization by “cracking” (where the poppet

lifts off the seat) at the nominal pressure-relief setting,

allowing pumped ﬂuid to recirculate internally from the

discharge side back to the suction side.

In order to maintain the integrity of the relief valve

setting, the E1-2 thru E1-82 relief valves are not

adjusted by means of an external jack screw. Rather,

seven relief valve settings are ﬁxed at the factory

and adjusted by changing the poppet and spring

combinations. See the pump designation system

section for details on available E1-2 thru E1-82 relief

valve settings.

RELIEF VALVE PERFORMANCE

The design of E1-133 and E1-222 is spring-loaded and

externally adjustable. It addresses the problem of over

pressurization by initially cracking, and eventually

full-bypassing at the nominal pressure-relief setting,

allowing pump ﬂuid to recirculate internally from the

discharge side back to the suction side.

To properly size the integral relief valve, it is important

to understand the difference between crack pressure

and full bypass pressure.

Crack pressure is the pressure at which the poppet just

begins to lift off the seat.This pressure is not affected

by variations in ﬂuid viscosity or pump speed.The

pump will provide full ﬂow rate at all pressures below

the cracking pressure. E1-2 through E-82 pressure relief

valves are sized based on cracking pressure.

Full bypass pressure is the pressure that occurs when

100% of the pump’s ﬂow rate is bypassing internally

through the valve and no ﬂow is exiting the pump. E1-

133 and E-222 pressure relief valves are sized based a

full bypass pressure.
