5.3 Applications
MTS pumps are screw pumps designed for the
pumping of cooling lubricants and cutting oils for
machine tool applications such as:
•
modern metal machining centres
• grinding and deep-hole drilling machines.
Pumps can transfer cooling lubricants with high
lubricating effect or high cooling performance based
on the customer's requirements.
5.4 Pumped liquids
The pumped liquids must not attack the pump
materials. The composition, oil content (ability to
provide lubrication) and cooling effect of the liquid
determine the pump maintenance intervals and
maximum permissible loading.
The permissible pumped liquids according to DIN
51385 are divided into three groups according to
water and oil content.
Solutions (L)
• Inorganic materials in water
• dispersions of organic and synthetic materials in
water.
Emulsions (E)
Oil in water, oil content E 2 % to E 20 %.
Cutting and grinding oils (S)
• without additives
• with polar, physically effective additives
• with mild-effect, lubricating film forming EP
additives
• with polar and mild-effect EP additives
• with active, chemical additives
• with polar and active EP additives.
6. Handling and storing the product
6.1 Handling the product
See section 2.2 Handling the product .
6.2 Storing the product
The pump has not been treated for storage from
factory.
6.3 Preparation for storage
Prepare the pump properly for storage both inside
and outside.
Use RUST-BAN 335, for example, as corrosion
inhibitor.
Applying corrosion inhibitor to the inside of the
pump
1. Close the suction-side flange with a blind flange.
2. Fill the pump with corrosion inhibitor.
3. Turn the shaft slowly by hand against the pump's
direction of rotation.
4. Continue filling and turning until corrosion
inhibitor comes out of the discharge-side flange
without bubbles.
5. Close the discharge-side flange with a blind
flange.
Applying corrosion inhibitor to the outside of the
pump
Apply corrosion inhibitor to all bare metal parts using
a brush or spray can.
6.4 Storage
1. Seal all openings with blind flanges, blind plugs
or plastic covers.
2. Make sure the storage room meets the following
conditions:
– dry
– frost-free
– vibration-free
– dust-free.
3. Turn the shaft once a month and make sure the
shaft and bearing change position in the process.
