H. NON-COMPLIANCE WITH SAFETY
INSTRUCTIONS. Non-compliance with safety
instructions may result in personal injury, property
damage, or unnecessary damage to the pumping unit.
Non-compliance with these safety instructions will also
lead to forfeiture of any and all rights to claims for
damages. Non-compliance, can for example, result in:
 Failure of important pumping unit functions.
 Failure of prescribed maintenance and servicing
practices.
 Hazard to personnel by electrical, mechanical,
and chemical effects.
 Hazard to the environment due to leakage of
hazardous substances.
Avoid Possible Non-Compliance. The following
specific safety precautions apply to the pumping unit:
 DO NOT exceed maximum discharge pressure
on discharge case (Refer to Table 1).
 DO NOT operate pump without fluid to seal or
packing.
 DO NOT run pump dry for extended periods of
time (longer than 1/2 hour)
 DO NOT run pump against a closed discharge

guards must be installed, the motor must be CE
marked and the completed machine reviewed
for compliance for applicable EHSRs before a
CE mark is attached.

III. EQUIPMENT DESCRIPTION.
Standard materials of construction are cast iron and
CD4MCu. Other metallurgies are available, such as
hard iron, monel, hastelloy, etc... Also available is a fully
rubber lined version for abrasive and extremely
corrosive application including the Flue Gas De-
sulfurization (FGD) process with high chlorides.
The bare pump consists of following major parts and
options. Please refer to Figures 9 and 10, assembly
drawings, for the location of parts identified by item
numbers.
Item 1 - Casing. The casing houses the impeller (2)
and consists of the discharge volute, suction cover (9),
