High-Capacity Solids Handling for Water, Sewage & Sludge
The Global Pump 6GST SAE Mount is a rugged trash pump developed for handling water, sewage, sludge and liquids containing suspended solids and other material. With a maximum flow of 3,000 gpm (681 m³/h), maximum total head of 202 ft (61.6 m), and solid-handling capability up to 3 in (75 mm), it is suited to demanding dewatering and fluid-transfer duties.
The standard unit is close-coupled through an SAE flange to a water-cooled four-cylinder diesel engine, creating a portable diesel trash pump configuration for construction, municipal and industrial sites. Alternative drives, including electric motors, are also available where a diesel trash water pump is not the preferred power arrangement.
Global Pump's Auto Prime system uses compressor-fed venturi priming to establish suction automatically. For projects evaluating a self priming trash pump, this automatic priming arrangement provides convenient operation while the dry-running mechanical seal supports periods when water is not present at the pump. Its large solids passage also allows the unit to function as a dependable solids handling pump in difficult applications.
Dutco supplies the 6GST trash pump for water, sewage and sludge applications, handling solids up to 3 inches. This heavy duty trash pump provides a surface-mounted pumping solution for sites requiring high flow, automatic priming and reliable operation across wastewater, dewatering and sludge-transfer duties.

Types
The 6GST SAE Mount can be configured with different priming, drive, mounting and material options. This allows the pumping package to be adapted according to site access, operating conditions, fluid characteristics and duration of operation.
6GST SAE Mount with Auto Prime
This configuration uses Global Pump's compressor-fed venturi automatic priming system. It is suitable for applications requiring rapid suction establishment and repeated unattended priming.
- Automatic compressor-fed venturi priming
- Suitable for intermittent or changing water levels
- Dry-running mechanical seal
- Practical self priming trash pump configuration for field pumping duties
6GST with Diaphragm Priming
Global Pump also lists a diaphragm priming system as an available priming option within the GST range. It provides an alternative approach where project conditions favour diaphragm-assisted evacuation of air from the suction line.
- Alternative to compressor-fed Auto Prime
- Supports dependable suction-line priming
- Suitable for portable pump installations
- This priming arrangement should not be confused with a diaphragm sludge pump, where the diaphragm itself performs the main pumping action
Diesel-Driven 6GST SAE Mount
The standard 6GST SAE Mount is connected to a water-cooled four-cylinder diesel engine through an SAE flange.
- Suitable for remote locations without fixed electrical supply
- Provides a portable diesel trash pump arrangement
- Optional fuel tanks can support extended run times
- Suitable where a mobile diesel trash water pump is required
Electric-Drive Configuration
Alternative drives, including electric motors, can be supplied when site infrastructure or operating requirements favour electrical power over diesel.
- Suitable for fixed or electrically serviced locations
- Reduces dependency on diesel fuel
- Retains the solids-handling performance of the 6GST pump
- Provides another drive option for the 6 trash pump
Skid-Mounted Configuration
The pump can be supplied on a skid for stationary, semi-permanent or site-based operation.
- Stable installation platform
- Suitable for industrial and construction sites
- Can be configured with extended-run fuel arrangements
- Practical for repeated dewatering and sludge removal pump duties
Highway Trailer Configuration
A highway trailer package is available with an integral fuel cell/chassis, lights, fenders, tie-downs, lifting bail and front and rear jacks.
- Supports transportation between pumping sites
- Suitable for emergency and temporary pumping
- Simplifies deployment across multiple locations
- Provides mobile heavy duty trash pump capability
Standout Features & Benefits

Automatic Priming Performance
- Global Pump Auto Prime establishes prime using a compressor-fed venturi system
- Supports operation where suction conditions and water levels fluctuate
- Helps reduce manual priming requirements
- Particularly useful for temporary dewatering, bypass pumping and wastewater duties
Field-Serviceable Seal System
- Front pullout cartridge seal can be changed quickly in the field
- Helps reduce downtime associated with seal servicing
- Dry-running mechanical seal supports demanding portable applications
- Simplifies maintenance of the sewage trash pump during site operation
Abrasion & Corrosion Options
- Optional CD4MCu stainless steel is available

Surface-Mounted Pumping Alternative
- The 6GST operates as a surface-mounted centrifugal pumping system rather than a submersible sludge pump
- Provides accessible controls, engine and service components above ground
- Can be selected where operators prefer surface equipment instead of submersible slurry pumps
- Offers another approach where a sludge vacuum pump would not provide the required centrifugal flow and head performance
Application Areas
Construction Dewatering
- Handles groundwater, surface water and site water containing suspended debris
- Trailer and skid options allow movement between excavation and construction zones
- High flow makes the pump suitable for large temporary dewatering requirements
Sewage & Wastewater Bypass

- Automatic priming supports fluctuating wet-well and suction conditions
- Provides a practical sewage trash pump solution for temporary bypass operations
Municipal Drainage & Flood Control
- Maximum flow of 3,000 gpm supports rapid removal of accumulated water
- Mobile configurations allow deployment to flood-prone areas
- The trash pump can handle water containing debris that may be unsuitable for conventional clean-water pumps
Sludge Transfer & Removal
- Suitable for transferring sludge and solids-bearing liquids
- Large solids passage reduces restrictions caused by suspended material
- Provides a surface-mounted sludge removal pump option for treatment and industrial facilities
- May be selected instead of a submersible sludge pump when above-ground servicing and engine-driven operation are preferred
Industrial & Process Water
- Suitable for high-volume transfer of water containing solids or other material
- Optional corrosion- and abrasion-resistant construction expands application possibilities
- Automatic controls can support changing liquid levels
Mining & Quarry Dewatering

- Highway trailer packages facilitate rapid transport between locations
- Sound-attenuated enclosure options are available where operating noise needs to be reduced
Sludge Pumping System Selection
- The centrifugal 6GST is intended for high-flow solids-bearing liquid transfer rather than functioning as a sludge vacuum pump
- It is also operationally different from a diaphragm sludge pump, which uses diaphragm displacement as its primary pumping mechanism
- Selection should therefore be based on required flow, total head, solids size, suction conditions and fluid characteristics rather than pump terminology alone
