These are single suction pumps with overall non clogging impeller. Pump can be officered in stationary as well as transportable
arrangements. The stationary arrangement is supplied with pump connector unit and connector unit is connected to pump support
bracket with rubber diaphragm to make it leak proof joint

Pump Casing
The radially split casing is provided with delivery nozzle cast integral with it. Suction is axial and delivery nozzle is central and horizontal.
Specially designed semi concentric casing results in reduced radial thrust and ensures vibration free performance. Wide volute passage
ensures non clogging operation of the pump.

Impeller
Impellers are of non clog type which allows smooth passage of solids. Impellers are with two or multi vanes in semi open and enclosed to
cater wide application.Following types of impellers are available.

N Two vanes enclosed type.

NB Two vanes enclosed type (reduced width)
Q 3 vanes semi-open type.
QM,QNM 2 vanes semi-open impeller (with cutting & tearing arrangement)
QT 3 or 5 vanes semi-open impeller (with cutting & tearing arrangement)
QMB 2 vanes semi-open impeller (reduced width with cutting & tearing arrangement)
NM Two vanes enclosed type with modified outlet width.

Shaft
The high tensile steel shaft accurately machined and ground is supported by two ball bearings in the motor above the impeller. Shaft is
designed to transmit the power without undue vibrations and deflections. The shaft is common for pump and motor of monoblock design.

Mechanical Seals
Double mechanical seal with back to back arrangement is provided to ensure no ingress of pumping liquid in the motor.

Optional Features
Pumps can be supplied with “cutter fan“arrangement at suction to agitate the liquid.
Semi-open impellers can be provided with specially designed wear plate for cutting and tearing of soft, long fibrous materials.

Bearings
Bearing are grease lubricated and sealed for life, hence maintenance free.

Direction Of Rotation
Direction of rotation is clockwise when viewed from motor top.

Drive
Motor is dry type submersible and cooled by liquid being handled.
Motors are air tested for leak proof operation.
Degree of Protection for Motor: IP68 as per IS: 2147
Class of Insulation: F
Voltage: 415 V +/-10%
Frequency: 50Hz +/- 5%
Type of Starting: DOL up to 9.3 KW 4 Pole and SDS beyond 9.3 KW 4 Pole.

Cable
A specially designed cable with 1.1 KV grade, annealed tinned copper conductor, insulated with Electron beam irradiated cross linked
elastomeric compound [compatible for continuous operation up to 120C] cores laid up with a proof cotton binder tape and sheathed
overall with electron beam irradiated cross linked HD HOFR [Heavy duty, Heat, Oil, Fire retardant] elastomeric compound and generally
confirming to IS: 9968, Part-I. The cable with this unique combination of insulating and sheathing material offers best resistance to acidic or
alkaline sewage medium and to the effluent gases coming out of the sump. The cable is more flexible than the PVC cable making coiling
and handling easier and light in weight compared to PVC cable of the same size.

Control Panel
Control panel consist of starter, switch, fuse and safety features.
Safety features are:
Single phasing prevention
Overload /under voltage/ reverse phasing relays
Moisture sensing unit for detecting ingress of moisture or water into the oil chamber
Liquid level controllers to avoid dry running
Thermister sensing unit for High temperature at the motor winding.

Flanges
Standard drilling to IS: 6392 table 15//BSEN1092 PN16
