Datasheet summary
NGL
PDF datasheet mirror for NGL (Calpeda Pumps). Verify with OEM before design.
Summary
Product identification
The NGL series consists of self-priming shallow-well pumps with a built-in ejector, designed for close-coupled operation.
Applications
- Drawing water out of a well.
- Lifting water containing air or other gases.
- Increasing water pressure from flooded suction applications.
- As a pressure boosting pump for central water systems with low pressure (local specifications must be followed if increasing network pressure).
- Garden use.
- Washing with a jet of water.
Operating limits
- Liquid temperature: 0 °C to +35 °C
- Ambient temperature: up to +40 °C
- Suction lift: up to 9 m
- Maximum permissible pressure in the pump casing: 8 bar
- Duty: Continuous

Performance
Performance curves for head (H) versus flow (Q) at n ≈ 2800 rpm are available in the official PDF. Self-priming capability graphs show self-priming time (t) versus suction lift (Hs). The NGL series is capable of lifting water from depths of 9 m in less than 3 minutes. Electrical performance data (P1 Max. power input, P2 Rated motor power output, current A) for various models and voltages are tabulated in the official PDF. See the official PDF for exact tabulated values.
Features
- Compact: Smaller than conventional pumps of a similar type, allowing installation in restricted spaces.
- Reliable: Robust design, forgiving of temporary abnormal operating conditions.
- Better Self-Priming: Capable of lifting water from depths of 9 m in less than 3 minutes.
- Low Noise: An exclusive diffuser design with a patented flow control device guides fluid to reduce turbulence and velocity, dampening flow noise.
- Safe: Fast air evacuation reduces the risk of air-pockets developing at the mechanical seal, preventing seal failure due to lack of flushing and cooling.
