11. Maintenance
Dosing pumps are produced according to the highest quality standards and have a long
service life. Nevertheless some parts are subject to wear and tear caused by its running
(e.g. diaphragm, valve seats, valve balls). To ensure a long operating life, visual inspection
is recommended regularly. Periodic maintenance protects the dosing pump and system
from unexpected downtime.
11.1 Lubricants
The diaphragm-dosing pump is designed to be maintenance friendly. The dosing pump’s
transmission is greased for life with a molybdenum-disulfide. Nonetheless the grease has
to be renewed after approx. 5000 hours of operation when under heavy operational use
such as under high environment temperatures and long running times. For this purpose
you can use for example: “Molykote BR 2 plus” or „OKS400“.
NOTICE!
The dosing pump motor is not to be greased with oil!
11.2 Maintenance of storage
The motor shaft storage are ball holdings caulked and greased for life. The other anti-
friction bearings in the transmission as well as the plain bearing of the diaphragm insert
are greased with the operational lubricant.
