PRODUCTS AND SPECIFICATIONS

Here is a handpicked collection of our products which will answer your business needs

Thin Rubber Diaphragms

Thickness in functional area of these diaphragms can be manufactured from 0.20 mm, with fabric reinforcement. Fuel gas (LPG / CNG) supply to the engine is constantly controlled by these diaphragms. Pressure acting on the diaphragm is very low and the diaphragm has to move up and down according to the pressure and activate the part connected to it to regulate the flow of the fuel gas. Hence diaphragm material & properties are critical to give consistent performance.
We have been supplying 7 varieties of these diaphragms since the year 2000 to Original Equipment Manufacturer and we are the only supplier for these diaphragms to many OEMs.
Depending upon customer requirement, diaphragms can be developed using any rubber material (specified by customer) and supplied.

Rubber Product: LPG-CNG Gas Kit Diaphragms

Highly resistant to LPG / CNG
100% Leak tested
High sensitivity even at low pressures
Original Equipment Quality
Thickness from 0.20 mm onwards with fabric reinforcement

Rubber Gas Kit Diaphragms

These diaphragms are also with thickness 0.20 mm with fabric reinforcement in functional area, It is used in CNG / LPG kits of van / buses. Rubber material which Highly resistant to LPG / CNG is being used, 100% leak tested and accepted diaphragms are only dispatched to customer.
Over the years, problems faced by customer are analyzed, improvements made in design & material to give trouble free operations of Gas kits.

Low Pressure Rubber Diaphragm - Manufactured Product

For certain low pressure applications, diaphragms without fabric reinforcement can be used. These are homogeneneous diaphragms and are cost effective.

High Pressure Diaphragm - Manufactured and Exported Product

This diaphragm is used in applications where pressure is high (kit inlet area from the cylinder) Wall thickness would be around 1mm & above. Since they are subjected to higher pressures, according to the pressure in which they are used, suitable fabric (Nylon / Polyester) & their thickness are used. Rubber material which Highly resistant to corrosion is used. Typically, these diaphragms are fabric reinforced. As per customer design these diaphragms are supplied.

Plain Rubber Diaphragm / Homogenous diaphragms

Homogenous rubber diaphragms without fabric reinforcement for relatively small pressure differentials.

Air Brake Chamber Diaphragm - Rubber Product - Manufactured and Supplied

Good quality Nylon fabric and Rubber

Well known diaphragm usage in automotive application is Air Brake Chamber Diaphragm. In the Air Brake assembly, compressed air deflates diaphragm, thus displacing a piston which in turn applies the brake on the wheel drum. This is also a critical application, because any leakage through diaphragm would affect braking efficiency of the vehicle, hence diaphragm material & fabric positioning is very critical. We manufacture & supply Air Brake Chamber Diaphragm (used in air brake system of the trucks / buses) for export market (against orders). Quality of our diaphragms are at par with OEM manufacturers (physical properties and functional requirements).
Good braking response
Size of Air Brake Chamber Diaphragms (Outer Diameter) Type - 12 140 mm (5.5 inches)
Type - 16 152 mm (6 inches)
Type - 20 165 mm (6.5 inches)
Type - 24 178 mm (7 inches)
Type - 30 203 mm (8 inches)
Type - 36 225 mm (9 inches)
Higher wall thickness (1.5 mm & above) diaphragms are used in many applications (pneumatic / hydraulic) to transform mechanical action / energy. Depending upon pressure acting on the diaphragm, thickness of the diaphragm shall vary & fabric reinforcement shall be given. Rubber material is selected based on the media in which the diaphragms will be used. Based on customer requirement, properties of rubber material, fabric to rubber bond strength shall be achieved.

Bellow

To cover a flexible / rotating any portion from dust / other material, usually bellow / boot is used. Depending upon their design they can elongate, bend – to care of the shape and to prevent dust / any foreign particle. Based on the location to be used, rubber material is selected. We are capable of manufacturing any kind of boot / bellow with any variety of rubber.

Exhaust Rubber Hangers

Heat and weather Resistant Rubber
Original Equipment quality
Good vibration absorption

Rubber Hanger is used to hold the exhaust pipe which runs from engine to back side of the vehicle. Based on temperature at the point of use, rubber material is selected, usually, EPDM is used, however, Silicon is also used near engine. Since year 2000, we have been supplying exhaust rubber hangers to Original Equipment Manufacturer (approximately 150000 numers per month). We have in house facility to test almost all the properties to be tested in Exhaust rubber hangers.
