Grundfos MTr puMps Cut spare parts Costs with Completely leak-proof pump

Leak-proof pumps are a top priority in any machining process. Leaking pumps may lead to costly downtime and in turn affect spare parts costs. However, the new MTR DBT pump effectively eliminates that risk.

DBT stands for “Drainage Back to Tank”. This means that the liquid remains in the tank where it is supposed to be – even if the shaft seal is worn out and starts to leak. In addition to being leak-proof,

the new MTR DBT pump features an innovative frequency drive motor that reduces energy consumption to further cut spare parts costs.

Benefits:∙ Downtime risk due to leakage is eliminated• Noriskofcontamination• Longerserviceintervals• Reductionofsparepartscosts
