Chemical centrifugal pumps

Tradition creates innovationMany decades of experience are incorporated in the centrifugal pumps from Lutz-Jesco. Special varnish lay-ers and highly resistant materials guarantee highest re-liability and long service life, even with most aggressive media. The product program includes motor pump units as well as standard pumps for many possible fields of application.

UniversalThe normal-priming chemical motor pump units MB with horizontal axis are designed particularly for low-viscosity, acidic and alkaline solutions with a low solid matter content. The head assembly of the single-stage pumps consists of high-quality plastic material and a hydraulically efficient spiral casing.

For highest requirementsChemical motor pump units BN are single-stage, nor-mal-priming pumps with horizontal axis. They are sup-plied completely with motor for a fast and easy instal-lation into the piping system. Suitable for capacities of up to 10 m3/h.

Smart setupChemical standard pumps N are single-stage, single-flow and normal-priming centrifugal pumps with spiral casing. Due to their modular structure the bearing sup-port can be removed without having to dismantle the piping connections and the motor. Smooth and vibra-tion-free operation because of the sturdy construction. For capacities of up to 300 m3/h.

Simply dive itPlastic pumps VTP - BBF are vertical immersion pumps corresponding to the proven and well-known two-pipe principle. The main components of the single-acting pump are assembled in block design (according to DIN EN 858). The immersed section of the pump is without seals and is especially suited to convey low-viscosity, aggressive acidic, alkaline and solutions tram depressurized tanks, open basins or reservoirs at flow rates of up to 80 m3/h.

Chemical centrifugal pumps for many possible fields of application

For highest requirements

Centrifugal pumps with magnetic coupling

Sealless and environmentally safeSince the pump is magnetically driven, no mechanical seals are required and therefore the pump housing is hermetically sealed from the environment.

No leakages are possible.

Easy maintenanceA few number of components and no special tools to change wearing parts, reduce necessary downtimes.

Operating safety and high efficiencyHighly efficient magnets allow high temperatures. Op-timally adjusted material combinations of the bearings reduce friction losses.

Ideal for pumpingAcids, alkaline solutions, mixtures of acids and alkalis, solvents, alkaline degreasing baths, galvanic bath, pho-to chemicals as well as radioactive, valuable and highly corrosive liquids and many other thin-bodied fluids.

Fields of applicationGalvanic and surface treatment, sewage and water treatment industry, chemical industry, general industry. electroplating, acid plant engineering.

Clear advantagesCentrifugal pumps in horizontal and vertical construction are especially used for pumping neutral and aggressive liquids as well as liquids containing solid particles. Centrifugal pumps have proven reliability, ensuring safety and reducing maintenance downtime.

Atex 100a:Lutz-Jesco horizontal centrifugal pumps, series TMR version GX are conform with ATEX 94/9/EC. They can be operated in hazerdous areas.

Chemical centrifugal pumps

Chemical motor pump units BN

The Motor Block Pump BN is flanged on directly to the three-phase motor with extended shaft. The shaft seal is a mechanical seal. Depending on medium and operat-ing conditions the seal faces are made of siliciumcarbid (SiC), bellows and secondary seals of EPDM or FPM, the metallic parts made of stainless steel (1.4571) or Hastelloy C-4 (.4610).
