Pump Floats Built Around Your Pump.
Custom HDPE pump floats designed for your pump model, discharge arrangement and operating environment. From small donut floats to larger pontoon configurations, Polyline tailors the flotation, support and protective features to your application.
The right fit goes beyond keeping a pump afloat.
Off-the-shelf floats can suit straightforward installations. Where your pump, discharge arrangement or site conditions need something different, custom fabrication gives you more control over the fit. Polyline designs the float around your equipment, considering pump dimensions and weight, discharge routing, protective features, handling and service access together.
Matched to your pump
Float dimensions, pump supports and clearances are configured around the selected pump model and installation requirements.
Protection where it matters
Protective baskets and clearance features can be incorporated to help shield the pump from debris and contact with the bottom, according to the application.
Discharge arranged to suit
Top, mid and bottom discharge configurations accommodate different pump designs, with space and connections considered for the discharge pipework.
Installation and servicing considered
Lifting arrangements, shore ties and access to the pump can be incorporated into the design to suit how the equipment will be installed, secured and serviced.
A familiar shape. A fit made for your pump.
Donut Pump Floats
Our donut-style floats surround the pump with a fabricated HDPE flotation body. The donut outer diameter (OD), basket inner diameter (ID) and mud foot can be tailored to the equipment and its operating requirements. Available in small, medium and large configurations, with top, mid or bottom discharge arrangements depending on the pump.

Small, medium and large configurations
The following examples provide a starting point for discussion. Final dimensions, float weight and supported load depend on the pump and selected configuration.
| Range | Example overall dimensions, L × W × H | Example float weight | Indicative load rating |
|---|---|---|---|
| Small | 1.8 × 1.8 × 1.4 m | 110 kg | Up to 500 kg |
| Medium | 2 × 2 × 2 m | Approximately 300–400 kg | 1,000–1,600 kg |
| Large | 3 × 3 × 3 m | 1,000 kg upwards | 2,500 kg upwards |
Send us your pump model and installation details so we can confirm the appropriate size and load allowance for the complete arrangement.
Configured around the way your pump discharges.
Top discharge
Float and support details arranged to accommodate the pump’s top discharge connection, associated pipework and service access.
Mid discharge
Clearance and connection arrangements tailored to pumps with a discharge outlet partway along the pump body.
Bottom discharge
A configuration developed around the lower discharge outlet, with provision for discharge routing and a removable hose arrangement where required.
Choose the details your installation needs.
Depending on the configuration, your pump float can incorporate:
- Perforated protective basket: A surrounding barrier that allows water through while helping screen larger debris.
- Basket bracing: Support tailored to the basket and pump arrangement.
- Mud foot: A feature to help maintain clearance beneath the assembly when it approaches or rests on the bottom.
- Lifting lugs and shackles: Lifting points arranged for the specified assembly and handling method.
- Shore ties: Attachment points for securing the float in position.
- Inspection and ballasting ports: Access incorporated where required by the design.
- Removable discharge hose: An optional arrangement for suitable bottom-discharge installations.
Features are selected around the pump and site requirements rather than supplied as a fixed package for every application.
Pontoon Pump Floats
Pontoons for bore pumps
Polyline also designs pontoon configurations for bore pump applications. Pump support, discharge routing and flotation are developed around the selected equipment and how it will operate at the site.
Discuss a bore pump pontoon →Pontoon-style floats for submersible pumps
For applications better suited to a pontoon arrangement, we can develop a float around the submersible pump and installation requirements. Our experience includes a pontoon-style submersible pump float created for a gold mine client. This design approach is available for adaptation to other projects.
