Product Summary

The AUTOCPm/CM100 automatic pump station from CGO is a complete, ready-to-install water pressurization unit combining a self-priming jet pump with a 24L diaphragm pressure tank, PS-9 pressure switch, 7 Bar pressure gauge, five-way brass connector, and flexible hose. Designed for residential, agricultural, and light commercial applications, this automatic pump station draws water from depths up to 9 meters and maintains steady system pressure through automatic start/stop control. Trusted by global B2B distributors and contractors, the AUTOCPm/CM100 automatic jet pump delivers practical performance with reduced maintenance demands and fast installation.

Detailed Description

The AUTOCPm/CM100 is more than a standalone pump — it is a fully integrated automatic pump station engineered by CGO to address the most common challenges in household and light commercial water supply: pressure instability, motor short-cycling, and multi-component sourcing complexity.

The system centers on a peripheral-type centrifugal pump paired with a 24-liter pre-charged diaphragm pressure tank. Unlike simple bladderless tanks that become waterlogged and force the motor to start and stop dozens of times per hour, the diaphragm design separates stored air from the water circuit. The pump motor activates only when system pressure falls below the PS-9 switch cut-in threshold, and stops once the cut-out pressure is reached. This controlled cycling pattern protects motor windings from heat stress and significantly extends the service life of the AUTOCPm/CM100 self-priming pump station in continuous-use environments.

The five-way brass manifold at the heart of this automatic pump system consolidates the pressure switch, gauge, tank port, inlet, and outlet connections in a single corrosion-resistant junction point — simplifying installation and reducing the number of potential leak sites in the finished system.

Key Product Features

Complete all-in-one package: Includes 24L diaphragm tank, PS-9 pressure switch, 7 Bar pressure gauge, five-way brass manifold, 1"×1" flexible hose, and 1.5m wiring harness — ready for immediate field installation.

Automatic start/stop operation: The PS-9 switch regulates pressure between cut-in and cut-out settings, giving this self-priming pump station true unattended operation capability.

Anti-short-cycling diaphragm tank: Maintains consistent air pre-charge to buffer minor demand without triggering the motor — a key durability advantage for the AUTOCPm/CM100 automatic jet pump.

Corrosion-resistant brass manifold: Resists dezincification in chlorinated municipal water, making this automatic pump station a reliable choice for tropical and high-mineral-content water markets.

Vibration-absorbing flexible hose: Reduces transmitted stress to rigid pipework, lowering noise and protecting joint seals in residential installations.

Engineering Advantages 

From a hydraulic design standpoint, the diaphragm pressure vessel architecture used in the AUTOCPm/CM100 automatic pump station represents a meaningful upgrade over plain steel tank designs. Standard steel tanks lose their air cushion through gradual absorption — eventually becoming fully waterlogged. When that happens, the self-priming pump station motor must cycle on for every drop of water drawn, causing thermal overload and premature capacitor failure.

CGO addresses this with a factory pre-charged diaphragm tank rated for standard working pressure, maintaining system pressure between draws without relying on residual air in a bare tank.

The brass composition of the five-way manifold is also engineered with export markets in mind. Brass resists dezincification — a corrosion mechanism triggered by chlorinated water common in South America, the Middle East, and Southeast Asia — making the AUTOCPm/CM100 automatic jet pump a durable long-term choice for distributors in those regions.

Primary Applications

The AUTOCPm/CM100 self-priming pump station suits a wide range of water supply scenarios:

Residential pressure boosting from rooftop or ground-level tanks and cisterns.

Garden, greenhouse, and small-scale agricultural drip irrigation with automatic pressure control.

Water supply distribution in small hotels, apartments, and light commercial buildings.

Shallow well and open storage tank extraction from vertical depths up to 9 meters.

Light industrial clean water circulation in equipment cooling and process water lines.

Commercial Value 

For international hardware distributors, pump wholesalers, and sourcing agents, the AUTOCPm/CM100 automatic pump station offers a bundled product value that single-unit pumps cannot match. One SKU covers the complete pump, tank, switch, gauge, and fittings package — cutting sourcing complexity, lowering return rates, and speeding up end-user installation.

CGO supplies the AUTOCPm/CM100 automatic pump station in standard 220V/50Hz configuration with 110V/60Hz available on request, covering major market regions across Europe, the Middle East, South America, and Southeast Asia. Stable production capacity, standardized component selection, and flexible order quantities make this automatic jet pump a reliable, high-margin product for distributors managing seasonal spikes or project-based volume requirements.

FAQ

Q1: Does the AUTOCPm/CM100 automatic pump station require manual priming at startup?
Fill the pump body with clean water through the priming port before the first startup. After initial use, the self-priming pump station retains residual water and handles re-priming on subsequent starts automatically.

Q2: How often should the 24L pressure tank pre-charge be checked?
CGO recommends verifying the tank air pre-charge pressure (typically 1.5 Bar at zero system pressure) annually using a standard tire valve gauge. Correct pre-charge keeps the AUTOCPm/CM100 automatic pump system running at design efficiency.

Q3: Can this automatic jet pump handle well water with light sediment?
The AUTOCPm/CM100 is designed for clean water use. CGO advises installing a fine-mesh foot valve at the suction inlet to protect the pump internals when drawing from shallow wells with minimal suspended particles.
