Hi, please advice me on the installation of MEMO pump. We have to install the one pump for the sludge feeding to belt press system in wastewater treatment system. Please find the following point; - underground tank(Sludge storage) depth is 3.5 m, so pump suction would be 3.3m depth - Although i have downloaded and read the instruction, i couldn't see this matter. Could you please clarify the following point; - maximum suction head (HS) of this pump type - which is the suction or discharge - Installation method

    6. Appendix 6.5 Lubricant quantities Note! After changing the lubricant, and in particular after the initial filling, the oil level may change during the first few hours of operation, as the oil galleries and hollow spaces only fill gradually during operation. The oil level is still within the permissible tolerance. If at the express request of the customer, an oil inspection glass is installed at an additional charge, we recommend that the customer corrects the oil level after an operating period of approx.

    1. Information 1. General information These Operating Instructions must be read before you transport, assemble, commission, maintain or repair NORD motors. All persons who are involved with such tasks must observe these Operating Instructions. All safety instructions provided in these Operating Instructions must be strictly observed for reasons of personal protection and protection of property.

  • Page 198: Description

    2. Description 3. Information 2.1 Field of Application Use of the motors: The motors may only be used for their intended purpose. The motors are designed with at least IP 55 protection (for degree of protection see name plate). They may be installed in dusty or damp environments. The necessary degree of protection and any additional precautions required always depend on the operating and environmental conditions.
