Grafner 700 W macerator, 9 m lift, 90 m run, four inlets, 80 °C review
The most completely specified macerator in the catalogue: lift, run, flow, four inlet sizes, an 80 °C limit, a carbon filter and its own external dimensions.
The bottom line The macerator you can actually design an installation around: every figure published, and the box measured. Only the noise is missing.
What you are getting
A 700 W macerator with a stainless cutter, four inlets — three at 40 mm and one at 100 mm — a stated 140 l/min, up to 9 m of lift, up to 90 m of run, an 80 °C inlet tolerance, automatic start/stop, a non-return valve, overheat protection, a backflow stop, a carbon filter on the vent, a full accessory pack and external dimensions of about 17 × 40 × 26 cm.
The most complete listing on the shelf
Lift. Run. Flow. Four inlet diameters. Temperature limit. External dimensions. Accessories itemised.
Every other macerator in this hub is missing at least two of those, and one of them contradicts itself about how many inlets it has.
What the 100 mm inlet buys
A WC. One macerator in this hub cannot take a toilet at all because all its inlets are 40 mm. This one has the WC connection plus three more, with couplings, clips and blanking plugs so the unused inlets are sealed properly rather than taped.
80 °C, the highest here
Washing machine, dishwasher, hot bath water — all within tolerance. The units here rated at 65 and 75 °C narrow what can be connected.
What is still missing
A noise figure, on the biggest motor in the hub. One macerator here publishes 30 to 40 dB; this one publishes nothing, and 700 W behind a bathroom panel is not silent.
The standing caveat
Every macerator makes drainage depend on the electricity supply. If this serves the only WC in a basement flat, a power cut is a real problem — and no listing on this shelf mentions it.

What we like, and what we don't
Strengths
Publishes lift, run, flow, all four inlet sizes, the temperature limit AND the unit's external dimensions — the most complete listing in this hub
A 100 mm WC inlet plus three at 40 mm, with couplings, clips and blanking plugs all supplied
A non-return valve, overheat protection and a backflow stop, all stated, with a carbon filter on the vent
Compromises
No noise figure, on the largest motor in this hub at 700 W
No discharge diameter as a figure, only the supplied angled piece
At 17 × 40 × 26 cm it needs real space behind a WC or under a basin — which at least you can now check

Questions people actually ask
Why do the external dimensions matter?
Because the unit has to physically fit behind the pan or inside the vanity. 17 cm deep, 40 cm wide, 26 cm high. It is the only macerator in this hub to publish them, and it is the measurement that stops a delivery going straight back.
What is the non-return valve for?
It stops what has been pumped up the rise from draining back into the tank when the motor stops. Without one the pump cycles repeatedly on the same water, which wears the motor and makes the noise happen twice as often.
