Jesco Centrifugal Pumps

Motor pump BN

Conveying chemicals safely

BN-type motor pump units are normal-priming, single-stage, plastic centrifugal pumps in block design with horizontal axis. Their dimensions and flow rates mainly correspond to DIN/EN 22858. The extended shaft of the drive motors directly carries the impeller. The pump head is flanged to the drive motor using an intermediate piece.

Standard pump N

Conveying chemicals safely

N-type standard pumps are normal-priming, single-stage, plastic centrifugal pumps with horizontal axis. Their dimensions and flow rates correspond to DIN/EN 22858. The standard use of extension coupling ensures simple dismantling of bearing supports and internal pump components without removing the pipe connections and motor. This avoids laborious alignment of the pump and motor when assembling the system.

Vertical Immersion Pump VTP BBF

Conveying chemicals safely

VTP centrifugal pumps in block design (BBF) correspond to the system of two-pipe pumps. Basically these immersion pumps are single-level immersion pumps with vertical axis the main components of which are combined according to the proven module system. The drive motor is located in the dry section above the fastening plate. The pump head is immersed in the medium.

Centrifugal pumps with magnetic coupling

CENTRAN TMP

Conveying chemicals safely

Lutz-JESCO America Corp’s CENTRAN TMP pumps are magnetically driven pumps, designed to meet the continuous demands of the marktplace. CENTRAN TMP pumps are centrifugal, horizontal axis, and close-coupled with the bodies built entirely of reinforced thermoplastic polymers. The internal components are ceramic oxides, HD carbon, and fluorinated elastomers which means any contact of metallic parts with the pumped fluid is avoided.

No dynamic shaft seals
Pump hermetically sealed
Version “R” suitable for limited dry running
Also suitable for liquids with high specific weight
Variable connections possibilities

CENTRAN TMB

Conveying chemicals safely

Lutz-JESCO America Corp’s CENTRAN TMB is a single stage, magnetically driven transfer pump with centrifugal impeller. TMB pumps includes five sizes that deliver flows from 3.96 to 18.49 gpm. The pump is made entirely of thermoplastics with outstanding chemical and mechanical resistance. The spindle is made of ceramic, the bearings are reinforced PTFE and the o-ring gasket is made of FKM. Leakage problems are eliminated since a drive magnet on the outside of the casing drives the magnetic impeller inside the hermetic casing.

No dynamic shaft seals
Pump hermetically sealed
