Safety Precautions

WARNING: READ THIS MANUAL COMPLETELY BEFORE INSTALLING AND OPERATING THIS UNIT. FAIL-

URE TO FOLLOW THESE PRECAUTIONS CAN RESULT IN SERIOUS INJURY OR DEATH.

WARNING: Magnetic field hazard: This pump contains powerful magnets. Exposed magnets (pump not connected to motor) produce power­ful magnetic fields. Individuals with cardiac pacemakers, implanted defibrillators, other electronic medical devices, metallic prosthetic heart
valves, internal wound clips (from surgery), metallic prosthetic devices or sickle cell anemia must not handle or be in the proximity of the magnets
contained inside the pump. Consult a health care provider for specific recommendations before working with this pump.

WARNING: Magnetic force hazard. This pump should only be disassembled and assembled using the recommended procedures. The mag­netic attraction is powerful enough to rapidly pull the motor end and the wet end together. Do not place fingers between the mating surfaces of
the motor and wet ends to avoid injuries. Keep the drive magnet and impeller assembly away from metal chips or particles, items with magnetic
stripes like credit cards and magnetic computer media such as floppy discs and hard drives.

WARNING: When pumping flammable or combustible liquids with a DB Series pump it is important to follow these guidelines:

1. You must use a PVDF pump. PVDF has conductive carbon fibers added which allow it to be grounded when installed in a properly grounded
piping system or when a properly installed grounding strap is attached to a housing bolt. If PVDF is not compatible with the liquid being
pumped, you should consider an ETFE lined UC Series magnetic drive pump.

2. You must select the non-sparking (Ns) bronze bump ring option. The non-sparking ring is pressed into the clamp ring or motor adapter and
prevents sparking should the motor bearings fail and the outer mag drive assembly runs out of round.

3. You must select an explosion-proof FTI motor or provide your own explosion-proof motor.

When pumping non-flammable or non-combustible liquids in a hazardous area using a DB Series pump, it is important to take these guidelines:

1. You must select the non-sparking (Ns) bronze bump ring option. The non-sparking ring is pressed into the clamp ring or motor adapter and
prevents sparking should the motor bearings fail and the outer mag drive assembly runs out of round.

5

2. You must select an explosion-proof FTI motor or provide your own explosion-proof motor.

WARNING: Hot surfaces. This pump is capable of handling liquids with temperatures as high as 220º F (104º C). This may cause the outer

areas of the pump to become hot as well and could cause burns.

WARNING: Rotating Parts. This pump has components that rotate while in operation. Follow local safety standards for locking out the motor

from the power supply during maintenance or service.

WARNING: Chemical Hazard. This pump is used for transferring many types of potentially dangerous chemicals. Always wear protective
clothing, eye protection and follow standard safety procedures when handling corrosive or personally harmful materials. Proper procedures should
be followed for draining and decontaminating the pump before disassembly and inspection of the pump. There may be small quantities of chemi­cals present during inspection.

WARNING: The pump and associated components are heavy. Failure to properly support the pump during lifting and movement could result
in serious injury or damage to the pump and components.

WARNING: Never run pump at less than minimum flow or with the discharge valve closed. This could lead to pump failure.

Installation/Operation Precautions

CAUTION: This pump should never be operated without liquid in the casing. It is recommended that run dry protection be used. Optional
electronic power monitors are available to help protect against run dry. If the pump has a PTFE, ceramic or silicon carbide bushing, IT CANNOT BE
RUN DRY WITHOUT CAUSING DAMAGE TO THE PUMP. However, the pump can operate without liquid in the casing if the pump has a carbon bush­ing. The exact length of time the pump can operate dry with a carbon bushing varies with operating conditions and the environment.

CAUTION: Never start or operate with a closed suction valve. Never operate with a closed discharge valve.

CAUTION: Always provide adequate NPSHa (net positive suction head available). It is recommended to provide at least 2 feet (61 cm) above

the NPSHr (net positive suction head required).

CAUTION: If pump is used on variable speed drive, do not exceed the frequency for which the pump was designed (for example, if the pump
is a 50 Hz model, do not exceed 50 Hz).

ADDITIONAL SAFETY PRECAUTIONS FOR ATEX COMPLIANT PUMPS

The pump is designed for

II 2GD
Ex h IIC T6…T4 Gb

Protection Control
A power monitor, flow switch, pressure switch or similar device must be used to protect against dry running, closed discharge valve or
decoupling. Any of these conditions could lead to a rise in surface temperature of the pump.

Construction Materials
Pump must be manufactured from PVDF with a PVDF motor adapter and bronze bump ring and have the designation “-A” in the pump part
number. The PVDF contains conductive carbon which allows it to be grounded when installed in a properly grounded piping system or when
a properly installed grounding strap is attached to a housing bolt. The bronze bump ring is pressed into the clamp ring or motor adapter and
prevents sparking should the motor bearings fail and the outer drive magnet runs out of round.

Grounding
Static sparking can cause an explosion. When operating in a hazardous area or pumping a hazardous fluid the entire pump system must be
grounded to prevent static discharge. Before operating the pump, ensure the electrical continuity throughout the pumping system and earth
ground is 1 Ohm or less. If greater than 1 Ohm, re-check all grounding connections.

Elastomer Selection
Proper o-ring material must be chosen for the fluid being pumped. Improper material selection could lead to swelling and be a possible
source of leaks. This is the responsibility of the end user.

Leaks
The pump must be checked for leaks on a regular basis. If leaks are noticed, the pump must be repaired or replaced immediately.

Temperature Classification
The surface temperature of the DB Series pumps depends upon the temperature of the fluid that is being pumped. The following chart lists
different fluid temperatures and the corresponding pump surface temperature.

Fluid

Temperature

Maximum Surface

Temperature

Temperature

Class

Maximum Allowable

Surface Temperature

21ºC (70ºF) 55ºC (131ºF) T6 85ºC

77ºC (170ºF) 76ºC (168ºF) T5 100ºC

104ºC (220ºF) 84ºC (183ºF) T4 135ºC

Cleaning
The pump must be cleaned on a regular basis to avoid dust build up greater than 5 mm.

Motor Rotation Test
Pump must be full of liquid with no trapped air in the suction and discharge lines before the rotation of the motor is checked. Do not operate
pump until it is full of liquid.

Start up
The pump must be filled from a flooded suction tank (gravity) or primed with liquid from an outside source. Open the inlet (suction) and dis­charge valves completely and allow the pump to fill with liquid. Close the discharge valve. Turn the pump on and slowly open the discharge
valve. Adjust the flow rate and pressure by regulating the discharge valve. Do not attempt to adjust the flow with the suction valve.

Maintenance
The recommended maintenance schedule depends upon the nature of the fluid being pumped and the specific application. If the pump is
used on a clean fluid, it is recommended that the pump be removed from service and examined after six months of operation or after 2,000
hours of operation. If the pump is used on fluids with solids, high temperatures or other items that could cause accelerated wear, then this
initial examination should be sooner.

After the initial examination of the internal components and wear items are measured, a specific maintenance schedule can be determined.
For best results, it is recommended that the pump be removed from service annually for examination.
