Pumps - specification

ČerpadloSTUFFING-BOX-LESS TANKS - ZVS SERIES

The stuffing-box-less tanks ZVS as intended for pumping agids, lyes, thin muds and all other wage liquids up to the temperature 150° C with the content of solid substances up to 30% of weight and the size of grain up to 7 mm. The pumps are suitable for pumping drinking water and food industry. The pumps are not self-suction pumps.

Construction:

The vertical centrifugal pumps powered with flange-mounted electromotor. The hydraulic part of the pump consists of circulating boiler, delivery body and balancing tank. The rotor is placed in bearing body in two anti-friction bearings. The construction is stuffing-box-less - during operation pumped liquid is sealed in a hydrodynamic way, at standstill the pump does not seal. The hydraulic part is connected with balancing tank that serves possible keeping pumped liquid during operation or for checking floding of impellor before starting operation.

Nominal lightness on delivery of DN 40 to DN 125. The connecting dimensions are PN6. The material variant - chromium-nickel-molybdenum stell. Other material finish upon agreement.

Advantages:

  • stuffing-box-less construction and bearing location enable failure-free operation
  • hydrodynamic princople of sealing and construction of pump enable operation without dripping pumped liquid
  • minimum impact on environment
  • operation at no load does not cause demage or wear and tear of pump

Delivery extent:

  • The pumps are delivered with flange-mounted electro-motors, normal design for tension 380 V, 50 Hz
  • The manufacturer will deliver spare parts according to the requirements pursuant to Table No.1
  • The manufacturer provide service and consultancy service
