Closed equipment arrangement
The enclosed design helps contain wastewater and grease within a serviceable system. Venting and odour management must still follow the approved project design.
GREASE SEPARATION + WASTEWATER LIFTING
Closed Automatic Grease Separator with Wastewater Lifting Station
An integrated solution for kitchens located below the gravity sewer level. Separate food solids and FOG, collect removed grease and lift wastewater within a closed equipment arrangement.
Selection noteProvide peak flow, fixture schedule, inlet level, discharge level, lifting head and available footprint.
Designed for basement kitchens and enclosed service areas
Commercial kitchens below the sewer connection level need both grease management and reliable wastewater lifting. Installing separate tanks, pumps and controls can consume plant-room space and complicate coordination. This closed integrated system combines staged separation, grease collection and wastewater lifting in one project-oriented arrangement.
CORE ADVANTAGES
Designed for selection, access and service
Integrated wastewater lifting
The lifting section is selected according to the required flow and total dynamic head. Pump duty and standby configuration are model-dependent.
Automatic grease removal
Separated grease can be transferred into an external collection container according to the configured operating sequence.
Food-solid pretreatment
An upstream screening or solids-handling section helps prevent large food residues from entering downstream sections.
Compact project coordination
Integrated equipment can reduce the coordination work associated with multiple separate devices, subject to the approved layout.
Service access
Maintenance panels, collection containers and control components are arranged for routine inspection and servicing.
HOW IT WORKS
A clear process path
- 1
Kitchen wastewater enters the pretreatment and solids-separation section.
- 2
Flow passes into the grease-separation chamber, where free-floating FOG is separated from wastewater.
- 3
Separated grease is transferred to a designated collection container.
- 4
Pretreated wastewater enters the lifting section.
- 5
The pump system discharges wastewater to the downstream sewer connection according to level-control signals.

FAQ
Before you request a model
When is a lifting station required?+
A lifting station is generally required when the kitchen drainage point is below the available gravity sewer connection or when the project cannot achieve the necessary gravity fall. The final requirement must be confirmed by the project drainage engineer.
How is the pump capacity selected?+
Pump selection is based on the design flow, total dynamic head, discharge pipework and required duty/standby arrangement. These values should be confirmed before quotation.
Is the system completely odour-free?+
The closed arrangement helps manage odour, but correct venting, sealing, cleaning and maintenance remain essential. No absolute odour-free claim should be made without defined test conditions.
Can the equipment pass through a standard plant-room door?+
Overall dimensions and access routes must be reviewed during selection. Where available, modular delivery or site assembly options can be evaluated for the selected model.
What maintenance is required?+
Routine work includes checking the solids section, grease collection container, pumps, level controls, vents, seals and internal chambers. The interval depends on kitchen loading and operating hours.
