Light vertical multistage centrifugal pump introduced
The RCDL/RCDLF is a highly versatile pump designed to handle a wide range of liquids, from tap water to industrial fluids. It can adapt to different temperatures, flow rates, and pressure conditions. The RCDL model is ideal for non-corrosive liquids, while the RCDLF is suitable for mildly corrosive media.
**Applications:**
- **Water Supply:** Used in water filtration, distribution, district partitioning, booster systems, and high-rise building pressurization.
- **Industrial Boosters:** Applied in process water systems, cleaning systems, high-pressure washing, and fire protection systems.
- **Liquid Transport:** Suitable for cooling and HVAC systems, boiler feedwater, condensate systems, and handling acids and alkalis.
- **Water Treatment:** Ideal for ultrafiltration, reverse osmosis, distillation, separation processes, and swimming pool systems.
- **Irrigation:** Effective for farmland, sprinkler, and drip irrigation systems.
**Working Conditions:**
- The liquid must be clean, non-flammable, and free of solids or fibers.
- Temperature range: 15°C to 70°C for hot water up to 120°C.
- Maximum ambient temperature: 40°C.
- Elevation limit: up to 1000 meters.

**Pump Description:**
The RCDL/RCDLF is a non-self-priming, vertical, multi-stage centrifugal pump with a standard motor. The motor shaft connects to the pump shaft via a pump head Coupling. A pull rod bolt secures the pressure cylinder and overcurrent unit between the pump head and the inlet/outlet sections. The pump can be equipped with an intelligent protection device to safeguard against dry running, phase loss, and overload.
**Motor Specifications:**
- Fully enclosed, air-cooled, two-pole standard motor.
- Protection class: IP55.
- Insulation class: F.
- Standard voltage options: 1X220-230/240V, 3X200-220/346-380V, 3X220-240/380-415V, 3X380-415V.
**Minimum Inlet Pressure (NPSH):**
Cavitation may occur if the pump inlet pressure falls below the vapor pressure of the liquid. To prevent this, ensure a minimum pressure on the inlet side. The maximum suction height H [m] can be calculated using the formula:
H = Pb × 10.2 – NPSH – Hf – Hv – Hs
Where:
- Pb = barometric pressure (set to 1 bar),
- NPSH = net positive suction head (obtained from the pump’s NPSH curve),
- Hf = friction loss in the suction line,
- Hv = vapor pressure of the liquid,
- Hs = safety margin (minimum 0.5 m).
If H is positive, the pump can operate at maximum suction. If negative, a minimum inlet pressure must be maintained.
**Parallel Operation:**
Using multiple pumps in parallel can offer several advantages:
- In variable flow systems, it helps match the system’s operating point.
- Increases reliability, as a single pump failure affects only part of the system flow.
