The Lowara ESHE 65-160/75/P25VSNW pump from XYLEM ITT Group is a single-stage centrifugal pump made of stainless steel, designed for pumping water and moderately aggressive liquids.

The most common seal type used in LOWARA ESHS pumps is the R-BT.FN.NU or R-BT-RN3.NU, a single, unbalanced mechanical seal with a conical spring.

The advantages of this seal design include its simple, efficient, and cost-effective construction, making it suitable for a wide range of applications.

The following material combinations are typically used:

• VBV (ceramic/carbon graphite/FKM) – for non-abrasive liquids with oxidizing properties, where no significant temperature fluctuations occur;
• VBE (ceramic/carbon graphite/EPDM) – for non-abrasive neutral liquids (primarily water supply applications), where no significant temperature fluctuations occur;
• QBE (silicon carbide/carbon graphite/EPDM) – for non-abrasive neutral or alkaline media, detergents, applications with possible dry running and temperature fluctuations (hot steam), temperature range from −50 °C to +150 °C;
• QBV (silicon carbide/carbon graphite/FKM) – for non-abrasive acidic media, oils, applications with possible dry running and temperature fluctuations, temperature range from −20 °C to +200 °C;
• QQE (silicon carbide/silicon carbide/EPDM) – for abrasive neutral or alkaline media, alcohols, and cleaning agents, temperature range from −50 °C to +130 °C;
• QQV (silicon carbide/silicon carbide/FKM) – for abrasive acidic media, oils, and lubricants, temperature range from −20 °C to +200 °C.
