2.5 Product-specific dangers
This chapter describes residual risks that have been identified in a risk
assessment. Safety precautions and warnings in this chapter and in
other chapters in the Operating Instructions must be observed in order
to avoid dangerous situations.
DANGER
Danger of injuries and property damage caused by leaks in
connections and the pump head
Poisoning and caustic burns, or undesirable reactions caused by
escaping hazardous materials
- Maintain the torque of connections
- Check tightening torque of head screws regularly
- Only use pump if it is in perfect working order
- Operate pump in accordance with the technical data
DANGER
Danger of injuries and property damage caused by medium
escaping from the discharge outlet
Poisoning and caustic burns, or undesirable reactions caused by
escaping hazardous materials
- Place the pump in a suitable collecting vessel
- Never close the discharge outlet
- If medium escapes from the pump's discharge outlet, stop
using the pump and contact your KNF dealer
WARNING
Danger of serious injuries or property damage caused by escap-
ing media in the event of overpressure on the suction side
Excessive pressure on the suction side will result in uncontrolled
escape of fluid, even if the pump is not operating
- Avoid overpressure on the suction side

2. SAFETY

2.6 Personal protective equipment
Special protective equipment must be used when performing certain
tasks. These are indicated separately in the individual chapters.
Where the wearing of protective equipment is concerned it is essential
to observe the safety data sheet for the medium to be transferred.
The following symbols appear in the working area or in the Operating
Instructions:
Safety gloves
to protect skin from contact with the transferred medium in accord-
ance with the safety data sheet.
Safety glasses
to protect the eyes from contact with the transferred medium in
accordance with the safety data sheet.
Face protection
to protect skin and eyes from contact with the transferred medium in
accordance with the safety data sheet.
2.7 Safety equipment
2.7.1 Discharge outlet
DANGER
Danger of injuries and property damage caused by medium
escaping from the discharge outlet
Poisoning and caustic burns, or undesirable reactions caused by
escaping hazardous materials
- Place the pump in a suitable collecting vessel
- Check the discharge outlet regularly for leaks
- Never close the discharge outlet (see Fig. 1)
- If medium escapes from the pump's discharge outlet, stop
using the pump and contact your KNF dealer
If the pump diaphragm ruptures, the transferred medium is channelled
out of the pump through the discharge outlet (see Fig. 1).
2.7.2 Emergency Stop
Pulling out the mains plug acts as an Emergency Stop. If the pump is
installed permanently, an Emergency Stop and a maintenance switch
must be fitted.

2.8 Environmental protection considerations
All replacement parts should be properly stored and disposed of in
accordance with the applicable environmental protection regulations.
Ensure adherence to the pertinent national and international regula-
tions. This applies especially to parts contaminated with toxic sub-
stances.
Dispose of any packaging material that is no longer required in an
environmentally friendly manner. The packaging materials are recy-
clable.
Dispose of end-of-life equipment in an environmentally friendly man-
ner. Use appropriate waste collection systems for the disposal of end-
of-life equipment. Used pumps contain valuable recyclable materials.
2.9 Danger areas
When transferring corrosive, poisonous, ionising, flammable or biolog-
ical media, escaping medium may cause a hazard.
The danger area of the pump is to be limited by means of safety work
stations complying with DIN EN 12469 and DIN 12980, and collecting
tanks.
