TotalFlo TF117MS-18 Multistage Pressure Pump with Controller - High Flow Tank & Mains Boosting NZ

The TotalFlo TF117MS-18 is a multistage pressure pump with integrated controller, built for medium to larger pressure boosting applications — including poor mains pressure and tank water supply. At 117 lpm maximum flow, it delivers significantly more capacity than the single-stage TF40J and TF50J models.

Suitable for both suction lift and flooded suction applications. Loss of prime protection is built in. The 304 stainless steel wet end casing handles a range of water qualities, and the pump is tested in compliance with AS/NZS 4020 for use in contact with safe drinking water.

Bore water quality varies significantly. We recommend testing your bore water before selecting a filtration system — get in touch and we'll help you choose the right configuration for your supply.

Note: this product holds a 2-year replacement guarantee against manufacturing defect. There are no serviceable spare parts and no infield service — in the event of a fault, the unit is replaced.

How it works

The TF117MS-18 uses a multistage centrifugal pump with an integrated pressure controller. The multistage design — multiple impeller stages in series — builds pressure progressively, allowing it to reach higher head than a single-stage pump of similar power. This makes it well suited to pressure boosting where the mains supply is inadequate, or for tank water systems supplying larger homes.

The built-in controller maintains system pressure and provides loss of prime protection — shutting the pump down if it runs dry.

Suitable for: medium to larger household pressure boosting, poor mains pressure improvement, tank water supply, garden and irrigation, and general water transfer.

FAQ

How is the TF117MS-18 different from the TF40J and TF50J models?

The TF117MS-18 is a multistage pump — multiple impeller stages working in sequence to build higher head and deliver much higher flow (117 lpm versus 40–50 lpm). It's designed for medium to larger homes and pressure boosting applications where the single-stage models would be undersized.

Is it suitable for poor mains pressure?

Yes — the TF117MS-18 can be used to boost inadequate mains supply. All applicable local plumbing code requirements must be followed for mains connection.

Can it draw water from a tank below the pump?

Yes — the TF117MS-18 supports suction lift applications. A good quality foot valve on the suction line is recommended to maintain prime.

What does "loss of prime protection" mean?

If the pump runs dry, the controller shuts it down to prevent damage. This is particularly important for unattended operation on tank water supplies.

What is the 2-year replacement guarantee?

If the pump fails due to a manufacturing defect within 2 years, it is replaced. There are no serviceable spare parts and no infield repair service for this product.

What does AS/NZS 4020 compliance mean?

It means the pump has been tested in compliance with the standard for products used in contact with safe drinking water — covering materials and their effect on water quality.

Is the water temperature limit important?

Yes — the maximum water temperature is 35°C. This pump is designed for cold water supply only and is not suitable for warm or hot water applications.

Do I need a plumber to install it?

For permanent household or mains boosting installations, a licensed plumber is recommended. Get in touch if you're unsure what's involved for your setup.

Can I pair it with a water filter?

Yes. A filter upstream protects the pump from sediment and extends its service life. Get in touch for filter recommendations suited to your water source.
