Booster sets with 2 to 4 LCR pumps.

Product catalog summary

Introduction
The Lubi Aquapack 1000 booster sets are composed of 2 to 4 identical vertical multistage (LCR) pumps mounted in parallel on a common base frame. They include a control cabinet with motor protection and an integrated LE 1000 series controller. These systems are preassembled and tested, featuring essential components like suction and discharge manifolds, isolating valves, non-return valves, pressure gauges, and pressure switches. A diaphragm tank is necessary for stable operation.

Applications
These booster sets are designed for clean water transfer and pressure boosting in various settings such as community water supplies, apartment complexes, hotels, hospitals, industries, commercial buildings, and schools.

Features and Benefits
The Aquapack 1000 offers high efficiency, low NPSH, air handling capabilities, and features like spacer coupling, sleeve sealing, tungsten carbide bearings, and reinforced shaft lock rings. These features help minimize energy costs, improve suction capability, reduce dry-running risks, and enhance operational reliability.

Controllers
The LE 1000 Controller manages multiple pumps with features like cascade control, motor protection, and a PLC controller with a touch screen display. The LE 1000V Controller includes a Variable Frequency Drive (VFD) for energy efficiency and smooth operation, with additional features like "Zero Flow/Demand" to prevent unnecessary pump operation.

Operating Conditions
The system operates with a flow range up to 480 m³/h and a maximum pressure of 16 bar. It supports liquid temperatures from 0°C to +90°C and ambient temperatures from 0°C to +40°C. The maximum suction lift is calculated based on several factors including NPSH and safety margins.

Construction and Materials
The Aquapack 1000 is built on a common base frame with pumps fixed by bolts. It includes a discharge manifold, isolating valves, and non-return valves. The materials used include stainless steel and cast iron, with specific components like pump heads and impellers made from durable materials.

Installation
The system must be installed in a well-ventilated room, not exposed to direct sunlight, with adequate clearance for inspection. Proper pipework and vibration dampening are necessary to optimize operation and minimize noise and vibration.

Performance Curves and Dimensions
Performance curves for various LCR models are provided, detailing flow rates and pressures. Dimensions and weights are specified, with variations possible due to technological improvements.

Installation Guidelines

Expansion Joints: Recommended for suction and discharge pipes to prevent vibration transmission.
Foundation: Should be on a solid, even surface like a concrete floor. If vibration dampers are not used, the system must be bolted to the foundation.
Dampening: Use vibration dampers between the booster system foundation and building parts.
Electrical Installation: Must be performed by an authorized person following local regulations and should comply with enclosure class IP 55.

Design Specifications
The Aquapack 1000 booster sets come in different designs:

Design A: Control cabinet mounted on the same base plate as the pumps.
Design B: Control cabinet centered on the base plate.
Design C: Floor-mounted control cabinet.
Design D: Control cabinet mounted on a separate base plate.

Dimensions may vary by ±20 mm.

Booster Set Configurations
Details configurations for booster sets with 2, 3, and 4 pumps, including motor power (kW), manifold connections, and dimensions.

Diaphragm Tank Selection
Outlines the importance of selecting an appropriate diaphragm tank to ensure stable operation. The tank volume is calculated using a specific formula considering factors like mean flow, pressure differences, and maximum starts/stops per hour.

Key Parameters

Supply voltage: 3x380-415V
Motor power range: 0.37 kW to 30.0 kW
Manifold connections: R 2, R 2½, DN 80, DN 100, DN 150, DN 200, DN 250
Diaphragm tank constant (k): 0.9
Maximum starts/stops per hour: 30 to 100

Recommendations
Consider local regulations and system design specifications when determining the maximum number of starts/stops per hour. Ensure adequate space and ventilation for diaphragm tank installation.

Specifications
Provides specifications for diaphragm tank pre-charge pressure, set to 0.9 times the lowest cut-in pressure. Details the minimum diaphragm tank volume required at a pressure differential (Δp) of 1.5 bar for different pump types and cut-in pressures.

Procedures
Instructions for setting the diaphragm tank pre-charge pressure and selecting the appropriate tank volume based on the cut-in pressure and pump type.

Data Summary
Includes tables listing minimum diaphragm tank volumes in liters for various cut-in pressures ranging from 1 bar to 8 bar, and for different pump types (LCR 2 to LCR 90).
