Danger of injuries and damage to property due to leaks at the
interfaces to the pump head
Poisoning and chemical burns or unintended reactions caused by
leaking dangerous substances

Danger of injuries and damage to property due to uncon-
trolled flow while the pump is not in operation
Poisoning and chemical burns or unintended reactions caused by
leaking dangerous substances
 Construct the fluid system so that the operating pressure at
the pressure side of the pump is higher than at the suction
side.
 Install a shut-off valve in the fluid circulation system.
The risk analysis indicates a risk of explosion from materials and
substances.
Danger of injuries and damage to property due to an explo-
sion in the pump
The pump housing is made from aluminum. If the pump dia-
phragm is damaged, medium can accumulate in the housing and
form hydrogen (especially with acids and lyes). This could cause
an explosion in the pump housing.
 Check and monitor the reactivity of the medium with alu-
minum.
The pump housing is designed to withstand pressure surges
caused by explosions. The probability of a fault that would cause
an explosion is deemed to be low. When installed in the system,
the risks in the complete system must be assessed.
