Production Market
We serve markets in Italy, France, Switzerland, and Russia. We have been authorized by the Aturia Group—a pump company with branches in France, Switzerland, and Italy—as their local representative for sales, assembly, and service.

 

Our Service
After equipment installation, we perform commissioning (debugging) of centrifugal pumps to ensure normal operation. We also provide operational training to customers, guiding them in the correct use, maintenance, and care of centrifugal pumps to help extend the service life of the equipment.

 

Understanding Customer Requirements
Through detailed communication in the early stages, we strive to fully understand each customer’s needs and usage environment, including product categories, specifications, performance requirements, and working conditions.

FEATURES

 

According API 610 (VS4).

Double volute casing above 80mm reduces radial loads.

Low NPSHr suits many duties.

Modular line shaft – Lengths up to 8m.

Easy maintenance Spacer coupling permits inspection of top bearings, replaceable wear plate.

Top mounted mechanical seal option.

Media or external lubrication option.

Space saving construction.

Circular or rectangular cover plate to suit.

 

Packing Seal

Although there is no pressure at suction and discharge, in case of overpressure of flush fluid to splash to the air from the base, soft packing must be used.

Shaft connections

Long shaft is machined in two sections or more, end of one shaft screwed rod, the other one is machined with inner screw, two shafts are connected with screws, outside fixed with joint key and shaft bush. Torque is transferred by joint key, thrust force is transferred by screwed rod, this improves coaxiality of the pump shaft, at the same time, make it more easier of machining the long shaft.

Support type

LY series pumps are adopted multiple points support, angle-contact ball bearing is used above the liquid, every short shaft under liquid is supported by sliding bearing, sliding bearing is fixed on the middle supporter, with which supporting pipes are connected.

Balance housing structure

Balance housing is made up of pump casing and middle supporter, there is balance pipe at the bottom of the housing to connected to the air, for releasing pressure and reducing thrust force of the pump set. At the same time, solid liquid can be passed through the balance pipe to prevent solid liquid leakage up from entering sliding bearing. Under the lower sliding bearing, there is packing seal to prevent solid liquid leakage up again.

Applications

Transfer solids and corrosive liquid as slurry pump.


Rolling mill.


Chemical process.


Sewage treatment.


Transfer pump for flammable and explosive liquids.

 

Performance range
 

Capacity Q 2-400m3/h

Head H 5-100m

Working temperature T -20~ +200°C

 

 

Structural

Safe and reliable connecting shaft structure.

 

Adopt multi-points support for the rotor component and pumps runs safely and reliably.

 

Adopt external or self-lubrication for sliding bearing.

 

The impeller has submerged into medium when the pump begins to run,so start up become easy without air evacuation.

 

Adopt two-runner casings(the diameter is graeter than 80mm).It is small of radial force of rotors component, of shafts deflection and of wear and tear from sliding bearings,so long service life.

 

The pump runs clockwise looking from the motor end.
