Drainage Pumps
Drainage Pumps · Technical Overview
The series manufactured by JOVAL — JRD and JRV at three power levels (0.55, 0.75 and 1.1 kW), in single-phase 230 V and three-phase 400 V variants — cover flows up to 30 m³/h and manometric heads up to 16.5 m, with discharge outlets from 1"½ to 2". Components combine AISI 304 stainless steel for the shaft, screws and motor jacket with cast iron for the body and impeller, ensuring durability when handling aggressive liquids. The M and T variants integrate a level float for automatic control in domestic and commercial pump pits.
For applications beyond the in-house range, JOVAL integrates a curated complementary range from European partners: small-frame vortex and twin-channel (WFD) for light domestic installations, industrial single-channel and vortex (Patrol and Titan) for more demanding loads, grinder pumps (PVT) for sewage with fibrous matter, heavy cast-iron (QXN) for industrial drainage and construction site dewatering, and Baby Battery 12/24 V DC for emergency use. This combination covers the full spectrum of drainage applications under a single technical specification.
The JRD and JRV series are tested on our in-house hydraulic test rig at the Fafe factory, under an ISO 9001:2015 quality system. Technical support is provided directly by the factory, with permanent stock held in Portugal for both the in-house series and the complementary range.
Frequently asked questions
-
What is the difference between the JRD and JRV pumps?
The JRD is for drainage of water with low solids content (cellars, garages, sumps). The JRV is designed for domestic wastewater with particles, with an impeller suited to higher solids tolerance. Both come in 0.55, 0.75 and 1.1 kW.
-
How does automatic level start with a float switch work?
Models with the M and MAQ suffix include a float that starts and stops the pump by level. For fixed twin-pump installations with alternation, JOVAL also manufactures the BA2CF control panel for wastewater.
-
When should I use a grinder or a heavy cast-iron pump?
The grinder pump (PVT series) shreds fibrous matter before pumping domestic sewage into pressure lines. The heavy cast-iron QXN series is for industrial drainage, construction site dewatering and deep sumps. Both belong to JOVAL's complementary range.
-
Can the JRD/JRV be used in septic tanks?
Yes. The JRV is designed specifically for domestic wastewater with particles, making it the JOVAL-made choice for low-flow septic tanks. For tanks with high fibrous content, the complementary PVT grinder series is recommended instead.
-
How do I size the flow and head for a domestic installation?
Calculate the inflow to the pit and the geometric lift to the discharge point, adding pipework friction losses. For 5 to 20 m³/h and head up to 16 m, the JRD/JRV range covers most domestic installations.
