Product group · 01

Hot Oil Centrifugal Pump

Circulates or transfers high-temperature heat-transfer oil in systems such as chemical processing, power generation and oil and gas facilities. Selection is based on the fluid properties at the actual operating temperature, not ambient data.

Published limits

Max flow: 250 m³/h Max pressure: 8 bar Max operating temperature: up to 350 °C
Technical note: maximum flow and maximum pressure are published individual limits and are not achieved simultaneously at a single duty point. Final flow, head, power and materials are fixed by the approved performance curve and project documentation.

What to consider

  • Thermal expansion: casing, shaft and supports are sized so the pump starts, runs and shuts down without mechanical binding at operating temperature.
  • Materials and seals: wetted materials and sealing arrangement must be compatible with the heat-transfer oil chemistry at its working temperature.
  • Hot commissioning: startup procedures must bring the pump and casing to operating temperature before full flow is applied.
  • Fluid properties at temperature: viscosity, density and vapour pressure change with temperature and drive the hydraulic selection.

Scope note: heat-transfer oil service is not automatically suitable for crude oil or other hydrocarbon mixtures. Each fluid requires its own review.

Portable Petro Fire Water-Mist Reciprocating Pump

A portable, gasoline-engine-driven reciprocating package with a gearbox, intended for high-pressure fire-suppression duty where the unit must be moved to the point of use. It is a field-portable device, not a fixed installation.

Published limits

Max flow: 2,000 L/h (2 m³/h) Operating pressure: approx. 180–200 bar
Technical note: the 180–200 bar range is an operating pressure. Confirm the exact rated and maximum pressure against the current datasheet — the two values differ and both matter for hose and nozzle selection.

What to consider

  • Portable deployment: unit weight, mobility and setup time matter as much as pump output.
  • High-pressure water mist: performance depends on the pump, hose, nozzle and the water supply feeding the unit.
  • Foam capability: foam service is possible only if the actual pump, dosing system and nozzle configuration support it. It cannot be assumed.
  • Fire class suitability: no single portable unit is effective for every fire class or every industrial or residential scenario.

Scope note: this portable package is not an NFPA 20 fire pump. NFPA 20 addresses stationary fire pumps with a defined driver, controller and test scope. The two are separate and are specified separately.

Stationary Fire Pump Package for Oil & Gas Projects

An industrial fire-water pump package for oil and gas facilities, designed around each project's fire-protection requirements and the applicable NFPA 20 criteria. Unlike the portable unit above, this is a fixed installation that forms part of the facility's fire-protection system.

What the package includes

  • Pump end: fire-water pump matched to the required flow and pressure at the system design point.
  • Driver: electric motor or diesel engine, selected to the site's power availability and reliability requirements.
  • Controller: sized and configured for the driver type and the project's control philosophy.
  • Installation and testing scope: foundation, suction and discharge piping, relief, and site acceptance testing, all evaluated for the specific project.
Technical note: performance, driver and controller specifications are defined for each project and confirmed in its approved documentation. NFPA 20 addresses the stationary fire pump, its driver and its controller. Compliance is confirmed at the project level against the applicable criteria, using the pump curve, driver data, controller configuration, installation drawings and site acceptance test records.
Trash flood centrifugal pump for flood response and accumulated-water removal

Product group · 04

Trash Flood Centrifugal Pumps

Portable centrifugal pumps for flood response and removal of accumulated water. Used where rapid deployment and reliable water removal matter more than high discharge pressure. Typical duty includes clearing flooded areas, dewatering pits and moving water containing modest amounts of solids and debris.

Available options and published limits

Sizes: 2", 3" and 4" Engine power: up to 13 hp Max flow: 120 m³/h Max pressure: 2.8 bar
Technical note: the 120 m³/h flow, 2.8 bar pressure and 13 hp power are published upper values for the range. Each of the 2", 3" and 4" sizes has its own approved curve. A single size does not simultaneously achieve every maximum figure, and selection must be based on the approved curve of the chosen size at the actual duty point.

Production milestone 1,000+ units produced

Cumulative production figure reported by Petropedam for the trash / flood centrifugal pump line.

What to confirm before selection

  • Model and approved curve: exact 2", 3" or 4" size, its discharge curve, and the actual performance at the site's static and dynamic head.
  • Solids passage and water quality: maximum particle size and debris content must be compatible with the selected pump's passage design.
  • Priming method: priming arrangement, suction hose length and vertical lift affect whether the pump performs as expected at the site.
  • Scope of use: the trash / flood pump is intended for water removal. It is not marketed as a firefighting pump.

How to specify your duty

Send the inputs below so the engineering team can recommend a pump configuration and the documents needed to confirm it. Not every question applies to every product — include the ones relevant to the group you are asking about.

Inputs to send

  • Flow: required duty flow, with minimum and maximum expected values.
  • Pressure or head: required discharge pressure or total head at the duty point, including static and dynamic components.
  • Liquid and temperature: fluid type (heat-transfer oil, water with debris, fire-water), operating temperature, and any chemical composition that affects materials.
  • Power source: electric supply characteristics, diesel availability, or gasoline-engine portability, as applicable to the product group.
  • Installation type: fixed or portable; suction arrangement; site elevation and lift.
  • Project location: site conditions, ambient temperature and any environmental or hazardous-area constraints.
  • Fire-system requirements (if relevant): applicable codes, required redundancy, controller philosophy and any client-specified test scope.
Frequently asked questions

Distinctions that matter

Is the portable water-mist pump the same as an NFPA 20 fire pump?

No. They serve different arrangements. The portable Petro Fire package is a field-portable, gasoline-engine-driven reciprocating unit intended for high-pressure water-mist duty. NFPA 20 addresses stationary fire pumps with a defined driver, controller and test scope. The two are specified separately, and the portable unit is not described as NFPA 20 compliant.

Can the hot-oil pump be used for crude oil or other hydrocarbons?

Not automatically. Heat-transfer oil service is a distinct duty. Crude oil and other hydrocarbon mixtures have different viscosity, vapour pressure and chemical properties at operating temperature, and each requires its own selection review.

Does the trash pump achieve its maximum flow, maximum pressure and maximum engine power at the same time?

No. The 120 m³/h flow, 2.8 bar pressure and 13 hp power are published upper values for the range. Each 2", 3" and 4" size has its own approved curve. Selection must be based on the curve of the chosen size at the actual duty point.

Can the portable water-mist pump be used with foam?

Only if the actual pump, dosing system and nozzle configuration support foam. Foam capability is not assumed; it must be confirmed as part of the fire-system design.

How can I confirm NFPA 20 compliance for the stationary package?

Compliance is confirmed at the project level against the applicable NFPA 20 criteria, using the actual package documents — pump curve, driver data, controller configuration, installation drawings and site acceptance test records. It is not established by marketing text or by a photograph.
