2.3 Applications

MTS pumps are screw pumps designed for pumping
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.

2.4 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.

3. Receiving the product

3.1 Inspecting the product

1. Unpack the pump on delivery and inspect it for
transport damage.
2. Report any transport damage to the
manufacturer immediately.
3. Dispose of packaging material according to local
regulations.

3.2 Handling and lifting the product

• Use lifting gear designed for carrying the total
weight to be transported.
• Fasten the lifting gear as shown in fig.
2.
• For vertical lifting, provide a safety rope between
the hook and the motor eyebolt.
• Never fasten the lifting gear to the motor eyebolt,
unless used as a safety precaution against
tipping over. This is especially relevant for units
with a high centre of gravity.
• Do not stand under suspended loads.
