Safety Information

Electrical Hazard

A pump is normally powered by an electric motor. This creates a hazard of

electrical shock which could cause severe injury or even loss of life.

To minimize the risk of this hazard:

All electric/electronic installation, maintenance, and service must be

performed by trained and authorized electricians only.

All electric/electronic installation must comply with all applicable codes and

standards including those established by OSHA (Occupational Safety and

Health Administration).

Do Not perform any maintenance or service on the motor or any other

electrical devices unless the electric power source has been turned off and

Locked Out using a locking device for which only the person involved in the

maintenance procedure has possession of the key.

Make installation suitable for a wet environment, including:

1. A power disconnect which can be locked in a power Off position and the

key removed. This will allow maintenance or service to be performed

without possibility of power being accidentally turned on.

2. Protection of all electric connections within a sealed junction box.

3. Proper grounding of the motor.

4. Protection from flooding. Do not install in an area which could fill with

water to a level which contacts the motor.

Warnings

381497 USA 10-2014

APV

Rotating Parts Hazard

Routine cleaning and maintenance procedures require pump disassembly.

The pump contains close fitting parts which rotate during operation. Should

the pump start unexpectedly while disassembled, severe injury could result.

To minimize the risk of this hazard:

1. Do Not assemble or disassemble the pump

2. Do Not remove the guard from the adapter

3. Do Not perform any maintenance or service on the motor or pump unless

the power source has been turned off and Locked Out, where only the

person involved in the maintenance procedure has possession of the key.

High Temperature Hazard

Some pump applications may require processing of high temperature liquids

and/or the use of high temperature cleaning/ sanitizing solutions. Pumping

high temperature liquids is considered to be hazardous and extreme care

should be taken when handling such liquids.

To minimize the risk of this hazard:

1. All installation, maintenance, and service of piping, valves, and other

controls must be performed by trained and authorized plumbers only. This

applies to process piping and cleaning/sanitizing piping.

2. All plumbing installation must comply with all applicable codes and

standards including those established by OSHA.

3. Do Not perform any maintenance or service on the motor or pump unless

the power source has been turned off and Locked Out, where only the

person involved in the maintenance procedure has possession of the key.

4. Never disconnect any lines or fittings (whether process or cleaning/

sanitizing) or disassemble the pump until the line is no longer under

pressure and the fluid inside is not hot or harmful.

5. Operating personnel must be authorized and trained.

Warnings

381497 USA 10-2014

APV

High Pressure Hazard

Fluids processed by a pump are under pressure. This creates a hazard to

personnel working in the area should a leak occur. Leaking high pressure

fluid may cause injury by startling personnel or from actual contact with the

leaking fluid.

To minimize the risk of this hazard:

1. All installation, maintenance, and service of piping, valves and other

controls must be performed by trained and authorized plumbers only. This

applies to process piping and cleaning/sanitizing piping.

2. All plumbing installation must comply with all applicable codes and

standards including those established by OSHA.

3. Never disconnect any lines or fittings (whether process or cleaning/

sanitizing) or disassemble the pump when lines are under pressure.

4. Should a leak occur, immediately find the cause and stop the leak.

Never operate the pump with both the inlet valve and the outlet valve in

closed positions. If the pump runs with liquid in it, while the valves controlling

the suction and discharge lines are both closed, the liquid in the pump will

heat up and turn into vapor, causing a risk of explosion.

To eliminate the risk of explosion, it is strongly recommended that the

following be included in the system:

1. A pressure relief device which relieves pressure and contains any

discharge, or

2. A thermal/pressure overload device to isolate the pump motor in the

event of excessive temperature/pressure.

Leaking Fluid Hazard

Fluid leaks or spills may occur in any pumping system. This creates a hazard

to personnel due to slippery floor conditions or contact with possibly

hazardous fluids.

To minimize the risk of this hazard:

1. Always clean up leaks and spills immediately.

2. Find and correct the cause of the leak immediately.

Warnings

381497 USA 10-2014

APV

The following important cautions describe ways to avoid incorrect operating

procedures which will cause serious damage to the pump.

Cavitation

Cavitation is a condition within the pump which results in extreme hydraulic

forces which can create a risk of severe damage to pump components.

Cavitation makes a characteristic "rattling" noise. It is caused by operation

with low fluid pressure at the pump inlet.

To minimize this risk:

Install and operate the pump so that NPSH (net positive suction head)

available to the pump equals or exceeds the "NPSH required" as shown on

the pump performance curve. To increase NPSH available:

1. Decrease the temperature of the liquid being pumped.

2. Increase the height of liquid supply level.

3. Decrease the suction line length and remove restrictions to flow such as

elbows, valves, etc.

4. Increase the suction line size (diameter).

5. Reduce the pump flow rate (throttle discharge).

Corrosion Pitting

Stainless steel is subject to a risk of corrosion when improperly cleaned or

sanitized.

To minimize this risk:

1. Never use steel wool or a wire brush to clean stainless steel surfaces.

2. Iron particles will embed and cause corrosion pits. Use a non-metallic

brush or scrub pad for cleaning when required.

3. Never allow prolonged contact of sanitizing solutions or other corrosive

cleaning chemicals with stainless steel. Only use sanitizing solutions

immediately prior to processing.
