Product data


IntroductionThe Lubi LBI series are non-self priming, horizontal,single-stage, centrifugal, end-suction pumps.

Pumps are available from 3 to 5 HP in single-phase andfrom 2 to 15 HP in three-phase power supply.

Motor and pump are close coupled in a convenient andcompact design for quick installation in limited space.

The pump is fitted with a maintenance-free, mechanicalshaft seal and single piece pump-motor shaft.

The pumps have axial suction port and radial discharge port.

ApplicationsFor suitable liquids which are thin, clean, non-explosive,non-aggressive, not containing solid particles or fibers.

For water supply systems and irrigation.

For heating, cooling, air-conditioning and circulation plants.

For civil, industrial and fire fighting applications.

As pressure boosting pump for central water systems withlow pressure (follow local specifications if increasing networkpressure).

Features and benefitsFollowing are the main features and benefits offered bythe LBI pumps.

• Compact design

• Easy and simple installation

• User-friendly operation

• Low noise level

• Reliable and robust construction

• Back pull-out design which simplifies inspection andmaintenance

Pumped liquidsThese pumps are designed for liquids like potable water,rain water or other than thin, clean, non-aggressive,non-explosive, not containing solid particles or fibres.

Sand contentMaximum sand content: 50 g/m³A higher sand content will reduce the pump life considerablydue to wear

Pump locationThe pumps have been designed to operate in a non-aggressive and non-explosive atmosphere.

The relative humidity should not exceed 95%.

Curve conditionsThe conditions below apply to the curves shown thefollowing pages.

• Tolerances in accordance with ISO 9906, Annex A.

• The motors used for the measurement are standardmotors.

• Test results with clean cold water, without gas content.Measurements have been made with airless water at atemperature of 68°F.

• Head and power values valid for liquids withdensity = 1.0 kg/dm³ & kinematic viscosity = max 1 mm²/s(1 cSt).

• The QH curves apply to a rated motor speed of 3450 .min ¹¯

• A safety margin of + 2 feet is recommended for the NPSHvalue.

MotorThe pump is fitted with a Totally Enclosed Fan Cooled,Cast iron 2-pole induction motor.
