PRODUCT INFORMATION

WQD-V Sewage Submersible Pumps. Float-controlled sewage drainage.

The WQD-V series is a single-phase sewage submersible-pump range intended for automatic drainage. The supplier describes a downward-swirling suction structure to reduce clogging, a float switch for unattended start and stop, and a capacitor-driven asynchronous motor with thermal protection. Suitability for corrosive liquids, grit, fibers and solids depends on the actual medium and confirmed wetted materials.

01Rated flow5–16 m³/h
02Rated head5–10 m
03Motor range0.18–1.1 kW

ENGINEERING DETAILS

Control, protection and operating limits.

The product introduction is summarized above. This section continues with the functional design, permitted operating conditions and model-code structure.

DESIGN & OPERATION
01

Downward-swirling intake

The supplier describes a downward suction arrangement intended to reduce blockage and improve drainage.

02

Automatic level control

A float switch starts and stops the pump with changing water level; provide enough free travel in the sump.

03

Single-phase drive

The WQD-V sheet identifies a capacitor-driven asynchronous motor for the listed single-phase family.

04

Thermal protection

The supplier describes a motor thermal protector for over-temperature events. Its additional over-pressure claim is not detailed on this sheet; verify control and restart behavior for the ordered unit.

CONFIRM BEFORE INSTALLATION
  1. 01

    The supplied sheet does not state a permitted immersion depth, liquid temperature, pH or maximum solids size; confirm these limits before specifying a site.

  2. 02

    Check outlet size, required flow and total dynamic head at the actual duty point rather than using maximum values as the rated condition.

  3. 03

    Allow unobstructed float-switch movement and confirm minimum wet-well level, anti-dry-run behavior and power supply for the exact model.

  4. 04

    Describe fibers, grit, chemicals and corrosive content so passage size, seals and wetted materials can be approved.

APPLICATION FIT

Is this the right pump family?

Use the application and construction check below before comparing model numbers. Final selection is always made at the actual operating point.

WASTEWATER INFRASTRUCTURE · INSTALLATION VISUALIZATIONSelected around the wet well, solids and discharge line.
BEST SUITED TO
01

Automatic sump drainage

Float-controlled operation where its travel and minimum water level are accommodated.

02

Domestic wastewater transfer

Confirm actual solids and liquid compatibility before choosing a model.

03

Small sewage wet wells

Select the pump at rated flow and total head, with the outlet arrangement checked.

04

Unattended drainage

Confirm thermal trip, power supply, restart and service access for the ordered configuration.

VERIFY BEFORE SELECTION
ControlFloat-switch start and stop
MotorSingle-phase capacitor-driven asynchronous
ProtectionSupplier-described thermal protector
Rated flow range5–16 m³/h in the seven listed models
Rated head range5–10 m in the seven listed models
Outlet1.5–2 in. depending on model

MODEL SELECTION

Compare the operating range.

Shortlist by flow and total head first. Motor power, connection and construction are verified after the duty point is known.

The supplied WQD-V table is reproduced as provided. Its V750F entry shows a 10 m rated head but a 9 m maximum head, which is internally inconsistent; confirm that entry and the unusual V1100F packing dimensions with the manufacturer before specifying either model.

The 30-part names come from your supplied original-factory WQ(D) threaded-outlet section. The expanded image is newly generated from that section and the WQD-V product photo; it is a realistic visual reconstruction, not the original factory CAD or a verified spare-parts drawing. Confirm the exact ordered configuration before service.
