Grinder Pumps
Grinder pumps for sewage and loaded waters.
Grinder Pumps · Technical Overview
The V series, distributed by JOVAL in Portugal, covers models from 1.1 to 1.5 kW (1.5 to 2 HP) in single-phase and three-phase versions, with a maximum manometric head of 12 m and flows up to 24 m³/h. Pump discharge ranges from 2" to 3" depending on the model, and the D / DF suffixes identify the direct-on-line variants and the variants with an integrated level float. The range is suited to off-grid dwellings without sewer connection, small lift stations with problematic inflow, and industrial installations where fibrous matter is unavoidable.
The choice between the V-series grinder and other impeller geometries — vortex or twin-channel — depends on the type of solids present. For a side-by-side comparison, see the main Drainage Pumps category, which also lists the PVT series (a second grinder line with a different power range). For duplex installations with automatic alternation, the natural complement is the BA2CF control panel manufactured by JOVAL, with digital protection in an ABS IP 55 enclosure.
Frequently asked questions
-
What is a submersible grinder pump and what is it for?
It is a submersible wastewater pump fitted with a rotating cutter at the inlet that shreds fibrous matter — wet wipes, sanitary textiles, food-waste fibres, hair — before the water reaches the impeller. It allows sewage to be pumped through small-diameter pressurised pipework (force main), which a conventional impeller cannot do.
-
When should I choose a grinder pump over a vortex or twin-channel pump?
Whenever the sewage contains unavoidable fibrous matter — wet wipes, sanitary textiles, food waste — that clogs or wraps around open impellers. Also whenever the installation needs pressurised pumping through thin pipework, where reducing solid size is a prerequisite for operation.
-
What are the flow and head limits of the V series?
The V series reaches up to 24 m³/h of flow and 12 m of manometric head, with powers between 1.1 and 1.5 kW. D models are direct-on-line; DF models include an integrated level float for basic level-based automation.
-
Does grinding use more energy than a normal pump?
It uses more energy than a vortex or twin-channel impeller for the same flow, because the cutting mechanism adds mechanical load on the motor. The cost is outweighed in installations where the alternative is repeated clogging and unexpected service downtime.
-
Can I install a grinder pump in a duplex configuration with alternation?
Yes. The usual complement for duplex setups is the BA2CF control panel (ABS IP 55) from JOVAL, for alternating command of two pumps. A second grinder line — the PVT series — is listed in the Drainage Pumps category.
