• 259 – Impeller / cutter configuration code

What applications is this pump suitable for?

This model is intended for pumping sewage and wastewater containing suspended solids and fibrous material. Macerator pumps are commonly used in residential, commercial and agricultural wastewater systems where solids reduction is beneficial before pumping through smaller diameter or pressurised pipework. These systems are often used where gravity drainage is impractical due to terrain, distance or site constraints.

What is a macerator pump?

A macerator pump uses a cutting or grinding mechanism to reduce the size of solids and fibrous material before the liquid leaves the pump. This can help reduce the risk of blockage in certain wastewater systems, particularly where smaller diameter discharge pipework is used.

Why would I choose a macerator pump?

A macerator pump may be selected where wastewater contains wipes, fibres or suspended solids that could otherwise cause repeated blockages. They are commonly used in pressurised sewage transfer systems where solids reduction is preferred over large free-passage hydraulics.

What are the disadvantages of a macerator pump?

Macerator pumps generally use more complex hydraulics than standard wastewater pumps and may not be suitable for abrasive slurries or applications with large quantities of grit and sand. Correct application selection remains important and performance should always be confirmed against the manufacturer curve and pumped media.

How is a P installation pump fitted?

P-designation pumps are intended for fixed guide-rail installations with an automatic discharge connection at the base of the wet well. The pump slides down guide rails and seals automatically onto the discharge connection when lowered into position.

This pump is supplied with a Flygt guide-rail fitting. In some cases, Flygt macerator pumps may also fit certain Lowara guide-rail arrangements, but compatibility should be confirmed before purchase.

Please send photos of your existing guide rails, base connection and discharge arrangement and we can advise on compatibility before purchase.

Can this replace my existing Flygt pump?

In many cases, yes. If you provide your existing model number or duty point, we can confirm suitability before purchase.

Please send photos of your current guide rails, base connection and installation arrangement and we can advise on compatibility and the most practical installation method.
