1.0 AIR QUALITY
Your Murzan Pump is powered with compressed air at a maximum pressure of 100 PSIG. DO
NOT EXCEED THIS LEVEL, as damage to the system or personal injury may occur.
Murzan pumps use a non-lubricated air valve system to meet the stringent USDA and FDA
standards required for pneumatically operated diaphragm pumps in the food and pharmaceutical
industries. Only a Murzan pump gives you this unique feature.
Murzan pumps have been engineered to provide the highest standard of performance and
reliability in handling your sanitary products. We at Murzan insure the most hygienic system
possible by equipping all Murzan pumps with an oil free, non-lubricated air valve. The patented,
non-lubricated Murzan air valve does not exhaust contaminated oil vapor into your plant
environment, unlike a lubricated air valve. A clean, well-filtered air supply is essential for the
proper operation of the air valve and for the prevention of contaminants being expelled into the
plant environment. A dirty oil laden air supply is by far the most expensive and overlooked
problem we find in working with our customers.
Oil and other contaminants that enter the pump drastically reduce the life of the air valve, shaft
bushing assembly, shaft, and block gaskets. The results are a much higher frequency of parts
replacement and repair, with a corresponding increase in maintenance expenses. As pump parts
become worn due to contamination, the pump looses efficiency and requires increased air
volume to move the product. This puts additional strain on the air supply and brings increasing
amounts of oil to the pump. The use of filters will pay for themselves in a very short time
through reduced parts usage and maintenance man hours.
