Model Parameters

Product Overview

The CGO VCP series is a compact vertical centrifugal pump built for reliable clean water conveyance across HVAC, irrigation, and light industrial settings. Covering a power range of 0.37 kW to 0.75 kW, each model integrates an aluminum pump body, aluminum impeller, and an energy-efficient motor into a space-saving vertical configuration. With maximum heads up to 36 m and flow rates reaching 4.2 m³/h, this water circulation pump fits mid-rise building services, agricultural distribution networks, and process cooling loops where consistent, low-maintenance fluid handling is the core requirement.

Key Features 

Compact Vertical Layout: The VCP vertical centrifugal pump runs on a vertical shaft orientation, cutting the floor footprint versus horizontal pump alternatives. That makes it a practical fit for tight plant rooms, basement mechanical areas, and rooftop equipment bays where every square meter counts.

Full Aluminum Construction: Pump body, motor housing, and impeller are all high-grade aluminum alloy castings. This delivers a sturdy yet lightweight unit — helpful for installations where crane access is limited — and aluminum's thermal conductivity aids motor heat dissipation during extended continuous runs.

Optional 304SS Motor Shaft: Standard builds ship with carbon steel shafts that cover the vast majority of clean-water duties. For jobs where the fluid chemistry sits on the borderline — lightly treated recirculating water, for example — a 304 stainless steel weld-on shaft is available on request, widening compatibility without a full wetted-parts overhaul.

Integrated Thermal Protector: A winding-mounted thermal protector tracks motor temperature in real time and opens the circuit if heat builds beyond safe limits. This self-protection function is genuinely useful in unmanned pump rooms and remote irrigation stations that run overnight without supervision.

IP44 Enclosure, Class B Insulation: IP44 blocks solid particles and omnidirectional water splash — enough for covered outdoor positions and HVAC plant rooms. Paired with Class B winding insulation and S1 continuous duty rating, this aluminum centrifugal pump handles ambient temperatures up to 40°C without derating, a specification that resonates with buyers in Southeast Asia and the Middle East.

Multi-Voltage Availability: Standard supply is 1-phase 220V / 50Hz. CGO also builds 110V / 60Hz and 220V / 60Hz variants on request, so global procurement teams can fit this compact water pump into local electrical infrastructure without sourcing additional step-down transformers.

Technical Advantages

The range covers three models differentiated by power and hydraulic output. VCP370 runs at 0.37 kW (0.5 HP) and delivers up to 3 m³/h at a maximum head of 21 m — the right fit for small recirculation loops and single-floor boosting. VCP550 steps up to 0.55 kW (0.75 HP), pushing 3.6 m³/h to 24 m, suitable for mid-size HVAC buffer circuits. VCP750 tops the range at 0.75 kW (1.0 HP) with 4.2 m³/h flow and 36 m head, covering multi-floor distribution and light-pressure industrial loops. All three models share a maximum suction lift of 8 m, a liquid temperature ceiling of 60°C, and external ventilation cooling. Inlet and outlet connection sizes are ¾ inch on the VCP370 and VCP550, stepping to 1¼ inch on the VCP750 to accommodate its higher flow rate.

Application 

The VCP water circulation pump handles clean, particle-free liquids that are chemically inert to aluminum and carbon steel. That scope covers a broad set of sectors:

Building Services and HVAC: Chilled and hot water circuits in fan coil systems, air-handling units, and central heating buffer tanks. The VCP compact water pump's small footprint simplifies installation in mechanical rooms that are already tight on space.

Agriculture and Irrigation: Drip lines, micro-sprinklers, and greenhouse watering networks in regions where a lightweight, single-phase vertical centrifugal pump that runs on standard domestic power is preferable to larger three-phase alternatives.

Civil and Light Industrial Use: Domestic pressure boosting, small commercial water supply, machine tool coolant recirculation, and secondary process loops in light manufacturing where clean fluid flow at moderate pressure is required on a continuous basis.

Commercial Value

CGO builds the VCP range under tight dimensional tolerances, which means hydraulic performance stays consistent from one unit to the next. For facilities running several vertical centrifugal pumps in parallel — a common setup in large HVAC plants and irrigation ring mains — that unit-to-unit predictability makes system commissioning and long-term balancing significantly easier. The aluminum centrifugal pump's lighter weight compared to cast-iron alternatives also cuts rigging and labour time on site. Add in the thermal protection that guards against unattended motor burnout and a voltage range that spans the major global supply standards, and the VCP series makes a compelling case for mechanical contractors and OEM integrators who need a dependable, globally sourceable compact water pump without excessive overhead cost.

FAQ

Q: Can the VCP vertical centrifugal pump handle mildly chlorinated water, such as in a cooling tower makeup circuit?
A: The pump is rated for fluids chemically inert to aluminum and carbon steel. Mildly chlorinated water with balanced pH typically falls within the acceptable range; heavily chlorinated or saline media is outside the intended scope. Specifying the optional 304SS shaft weld-on improves corrosion margin for borderline chemistries.

Q: Is horizontal mounting an option?
A: No. The VCP is designed as a vertical centrifugal pump — the bearing layout and external ventilation cooling are both engineered for a vertical shaft. Horizontal installation is not supported and would compromise the pump's rated performance and service life.

Q: How do I order a non-standard voltage variant?
A: CGO produces 110V / 60Hz and 220V / 60Hz versions of the compact water pump alongside the standard 220V / 50Hz build. Simply state the required voltage when submitting the enquiry, and the factory will confirm lead time and configuration.
