JL Circulation Heating Pumps

JL Circulation Heating Pumps

Application FormsealBuy

 


Circulation flange-type pumps (with in-line nozzle installation) are designed to be used in heating systems of both closed and open type with positive circulation of heating medium.

Circulation pumps for cold and hot water supply are applicable to direct installation on pipes of municipal and industrial heating systems, air-conditioning, cooling, and internal water systems.  

In contrast to wet rotor pumps, the contact between pumped medium and the motor while using this series is excluded. JL circulating pumps have inlet and outlet nozzles installed in one line and with the same nominal bore. JL circulating pumps are equipped with standard air-cooled flanged electric motors. 

 
Characteristics
  • JL circulation heating pumps are equipped with a unique specially designed motor. Furthermore, they feature improved construction that corresponds to international standards.
  • JL circulation heating pumps feature small size and small weight, which makes it possible to install them directly on the conduit of heating or water supply systems.
  • JL circulation heating pumps are equipped with a patented impeller that provides low energy consumption with high hydraulic characteristics.
  • Pump shaft is made of AISI 304 stainless steel.
  • Shaft mechanical seal prevents leakage.
  • Temperature of pumped medium ranges from -15 оC  to +120 оC (standard construction).
