Product Description

"PEW" Submersible dewatering pumps are vertically mounted, single suction, single stage (non-clog) pumps, designed to operate underwater.The low weight and compact design make them easy to transport.Once delivered to the site they can be used right away.These pumps are available in 3 impellar configurations:-

1. CLOSED
2. CUTTER AND
3. VORTEX

FEATURES

Heavy duty bearings
High efficiency copper wound motor
In-built lip seal to prevent ingress of silt and sand
Float switch is provided upto 0.75 kw - 1ph
Sewage pump Can handle solids upto 15mm & dewatering pump Can handle solids up to 30 to 60mm
The relatively small size and weight make these pumps specially suitable for temporary services like dewatering of construction sites and for emergency services in case of flooding.
The pumps at equipped with a handle which makes it easy to move them from one point of application to the other.
Pumps are designed for free standing installation, but can also be permanently installed by means of an auto coupling guide rail system
Pumps in permanent installations can cope with PH-values ranging from 4 to 10.
Permissible Liquid temperature: 0° to 40°C
All pumps are supplied with 15 meters cable up 3 HP pumps & 20 meters cable upto 5 to 10 HP pumps
The stator windings incorporate temperature sensors (PTC Or TOP) which cut out the motor in case of over temperature. (Temperature sensors (PTC OR TOP) are built into the stator windings, and a contact in the sensors will open on case of over temperature i.e. 120 oc.)
