Overview
Compact and reliable mechanically sealed pump
The CTP pumps are semi open single stage centrifugal pumps. Since there are no metal parts on the liquid side, the pumps are ideal for chemicals transfer and circulation in surface treatment industries.
CTP is a compact and reliable mechanically sealed centrifugal pump made in PP and PVDF. It is the right solution for liquids containing solid particles.

Working principle
PRINCIPLE OF OPERATION
PP & PVDF wetted materials
Can handle highly corrosive liquids also containing solids and metallic particles. Pumps can handle high temperature liquids. Alkali and acids. The version in PP-GF (glass fibre reinforced polypropylene) provides great mechanical strength and allows liquid temperatures up to 70°C. The PVDF (PolyVinylidine DiFluoride) version has superior chemical resistance and allows temperatures up to 80° - 90°C.
Semi open impeller
Allows pumping liquids with particles up to 3 mm and 10% in concertation. Compared to the pumps with magnetic coupling metallic particles are no obstacle for the CTP pumps. A semi open impeller also eases the transfer of liquids with higher viscosity.
Non-metallic pumps
The wetted components are non-metallic injection moulded thermoplastics enabling excellent corrosion resistance. The shaft is protected by means of a plastic sleeve and nut compatible with the pump housing material.
Mechanical seal
The spring is located on the dry side of the pump therefore all metallic parts are protected against contact with the liquid. This means no elastic bellow is required.
Safety drain
The special revision hole in the back casing provides a drainage from the mechanical seal in case any leakage occurs. This prevents the motor and shaft from getting into contact with the pumped liquid. The PVDF barb connector allows plug a hose and route the liquid out of the pump.
