DAB FEKA VS GRINDER 1000 MA Sewage Pump with Shredder

FEKA VS GRINDER 1000 MA is the automatic single-phase version of the DAB FEKA VS GRINDER: a submersible sewage pump with a stainless steel shredder, a vortex cast-iron impeller, 25 m maximum head, up to 14.4 m3/h and a pump certified to EN 12050-1 according to the sheet.

Shredding sewage into small-bore discharge lines

The FEKA VS GRINDER is described by DAB as a submersible pump for draining wastewater in commercial building service. Its shredder cuts the solids so the discharge can run through small-diameter pipes or against high pressures, which is the reason to choose a grinder pump instead of an open-vortex sewage pump when the rising main is narrow or long. The sheet states it is certified to EN 12050-1, the European standard for lifting systems for wastewater containing faecal matter in buildings and on construction sites.

The code ends in MA: the datasheet lists the 1000 MA (single-phase, automatic with an integrated float switch), the 1000 M-NA (single-phase, manual, no float) and the 1000 TNA (three-phase, manual). The 1000 MA starts and stops itself on the level of the tank, so it can run unattended in a collection pit.

Features listed by DAB

• Vortex impeller in cast iron with a stainless steel cutter and cutter base; the shredding system is AISI 630 stainless steel.
• Pump housing and base in cast iron; motor case, cap, seal-holder cover and handle in stainless steel.
• Double mechanical seal with an oil chamber: silicon carbide against silicon carbide on the pump side, carbon/alumina on the motor side; AISI 316 shaft.
• Motor cooled by the pumped liquid, on oversized greased-for-life ball bearings.
• Thermo-amperometric protection with the capacitor fitted as standard on the single-phase version.
• Outlet horizontal as standard, vertical with the curve kit accessory.

Materials

MA, M-NA or TNA

Choose the 1000 MA when you want the pump to start from its integrated float and have a single-phase supply. The 1000 M-NA is the same pump without the float, for use with an external level controller, and the 1000 TNA is the three-phase 380-415 V version (3 A, 1 kW), also without float. All three share the same hydraulic curve, so choose on supply and control, not on duty. The sheet lists the curve for a 1 mm2/s viscosity, 1000 kg/m3 density liquid; thicker sewage will reduce performance.

Installation

The pump can be fixed on a coupling device or stand directly on the tank bottom as a mobile unit, always vertical, to a maximum immersion depth of 7 m. For a vertical discharge you need the curve kit accessory. Use H07RN8-F supply cable and keep the float free to swing inside the pit. Connect the three-phase thermal protection to a control panel; the single-phase version has its own protection.

Typical uses around Oman

Hotel and apartment basements, restaurant and kitchen blocks, labour-camp toilets and below-grade bathrooms that cannot drain by gravity need a lifting station, and a shredder pump lets the contractor use a small-bore pressure main. Always size the pit and ventilate it according to the local drainage code, and confirm that your sewage does not contain wipes or plastics beyond what the shredder is designed to cut.

Selection and installation notes

A sewage pump is selected from the type of waste, the head and the pit size. Use a pit with a level control and an alarm, fit a non-return valve and isolating valve on the discharge, keep the discharge pipe size no smaller than the pump outlet and avoid sharp bends. Do not discharge rags, plastics or building waste, and lift the pump for inspection and cleaning at regular intervals.
