Model HDF2/HDF50 

IMPORTANT

Read the safety warnings and instructions in this manual 

before pump installation and start-up. Failure to comply with 

the recommendations stated in this manual could damage the 

pump and void factory warranty.

When used for toxic or aggressive fluids, the pump should 

always be flushed clean prior to disassembly.

Airborne particles and loud noise hazards. Wear eye and ear 

protection.

Before maintenance or repair, shut off the compressed air line, 

bleed the pressure, and disconnect the air line from the pump. 

Be certain that approved eye protection and protective clothing 

are worn at all times. Failure to follow these recommendations 

may result in serious injury or death.

ATEX compliant pumps are suitable for use in explosive atmospheres when the equipment is properly grounded 

in accordance with local electrical codes. Pumps equipped with electrically conductive diaphragms are suitable for 

the transfer of conductive or non-conductive fluids of any explosion group. When operating pumps equipped with 

non-conductive diaphragms that exceed the maximum permissible projected area, as defined in EN 13463-1:  2009 

section 6.7.5 table 9, the following protection methods must be applied:

•  Equipment is always used to transfer electrically conductive fluids or

•  Explosive environment is prevented from entering the internal portions of the pump, i.e. dry running

For further guidance on ATEX applications, please consult the factory.

When the pump is used for materials that tend to settle out 

or solidify, the pump should be flushed after each use to 

prevent damage. In freezing temperatures the pump should be 

completely drained between uses.

Before pump operation, inspect all fasteners for loosening 

caused by gasket creep. Retighten loose fasteners to prevent 

leakage. Follow recommended torques stated in this manual.

CAUTION

WARNING

Nonmetallic pumps and plastic components are not UV 

stabilized.  Ultraviolet radiation can damage these parts and 

negatively affect material properties. Do not expose to UV light 

for extended periods of time.

In the event of diaphragm rupture, pumped material may enter 

the air end of the pump, and be discharged into the atmosphere. 

If pumping a product that is hazardous or toxic, the air exhaust 

must be piped to an appropriate area for safe containment.

This pump is pressurized internally with air pressure during 

operation. Make certain that all fasteners are in good condition 

and are reinstalled properly during reassembly.

Take action to prevent static sparking. Fire or explosion can 

result, especially when handling flammable liquids. The pump, 

piping, valves, containers and other miscellaneous equipment 

must be properly grounded.

Safety Information

Grounding ATEX Pumps

WARNING

Pump not designed, tested or certified to be powered by  

compressed natural gas. Powering the pump with natural  

gas will void the warranty.

Use safe practices when lifting

kg

WARNING

The use of non-OEM replacement parts will void (or negate) 

agency certifications, including CE, ATEX, CSA, 3A and EC1935 

compliance (Food Contact Materials).  Warren Rupp, Inc. cannot 

ensure nor warrant non-OEM parts to meet the stringent 

requirements of the certifying agencies.
