Profitability in seals and swivel joints Due to the combining sealing systems, as well as 25 years of experience, NMF is in a position to offer the proper solution to solve sealing issues and to reduce the cost-of-ownership and downtime for its customers. Customised solutions is our daily job! Several product scan be supplied with certificates like the EC1935:2004, FDA compliance, TA-Luft, Fire-Safe, BAM, EN10204, etc. The frog is in our logo for a reason. When there is pollution, the frog is one of the first animals to suffer. With the frog we want to show we care for the environment and supply seals and swivels that do not leak during normal usage and are therefore environmental friendly and durable.

Lipseals in their most versatile form

� no “scoring” of the shaft! � pressure resistant to 8, 15 and even to 150 bar � rotational speed up to 40 m/s or 20.000 rpm � large variety in materials through modular form � very long life � when replacing run-in oilseals there is no need to

repair the shaft � low friction and therefore less wear

� lower power loss through less friction on the shaft

� easy to replace oilseals, stuffing box packing systems and mechanical seals

For prolonged life in pumps, mixers, gear boxes and many more applications

Mechanical seals for heavy duty

� pressure up to 8 bar and speed up to 8 m/sec � modular system for optimal adapting the seal to

the equipment � both positive transfer of torque and a large

depot for grease guaranty a long trouble free life � ready to fit cassette system, no adaption of the

installation necessary � with complete accessory and spare parts

program

For dynamic sealing of high-viscose, sticky and crust building media

Spring loaded seals for the highest tightness � spring loaded sealing systems according to TA-Luft /

VDI 2440 (approx. 100 bar, 450°C) and Fire-safe (160 bar, 750°C)

� long-time leak free due to spring supported compression of seal package

� TA-Luft conversion sets, complete with stuffing box packing, cover seal, spring sets and if required complete calculation checked by TüV for approval to TA-Luft suitability

For neutralising the stuffing box packing volume reduction due to usage, wear and aging

Dynamic seals for a long l i fe and an optimal operational certainty and profitabil i ty


The products in the NMF program comprise of a very complete package of special seals and swivels joints. Since dozens of years the sealing systems are used in the general-, chemical-, petrochemical- and steel industry, for paper production, agricultural, paints, water purification, machine building and food production installations. Important advantages are the life prolonging properties and the improved seal capacity, together leading to an improved seal system with higher reliability and a reduction in cost-of-ownership and downtime.

Camprofile gaskets third generation

� super elastic sealing element with an improved elastic recovery capacity

� reduced warehouse cost by integrating two or more pressure groups in one seal due to a break-away edge (patented)

� in compliance with EN 1514, EN 12560 as well as TA-Luft compliance

� ring-joints, spiral wound seals, welding seals and other special seals up to a diameter of 6 meter

� modern flange calculation software with standards according to EN 1591-1:2001, AD-Merkblatt 2000 B7/B8; ASME Code s.VIII and 4 more standards

To insure a tight flange coupling: flange calculation software for calculating the complete sealing system of the flanges

Special gaskets for installations in the high pressure and high temperature range

� spring loaded and blow-out safe seals according to the tension released construction principle

� spiral wound and carrier seals with a large resilience

� individual solutions for the optimization of a sealing system in e.g. for a manhole or high pressure heat exchanger

� including engineering, assembly and TüV approved and stamped documentation

To insure that regularly appearing fluctuations in pressure and temperature do not influence the sealing system and production process

Services at the installation

� conversion of valves to the TA-Luft-standard � repair, adaption, sealing and conversion of pumps

and valves to our seal system � measuring flanges with laser optics, assembly with

stretch bolt system � optimization of installations by hardening surfaces

with a layer welded on by laser � high chemical resistance, different layers are

available

Life prolonging, wear reduction, breakage preventing: use laser coted surfaces

Static seals in a large variety for control l ing extreme sealing situations


Swivel joints and rotary joints for complex and standard applications

Swivel joints in their most stable form

� for both liquid and gaseous media as rotating parts of the installation

� give pipes their proper position � available from 1/4” to 42”, in steel and stainless

steel � customisation possible due to a modular system � variable connections � movable arms as alternative for hoses � multi canal swivel joints on request with electrical

swivel joint to relay signals or power

For a reliable transport of media in a large variety of circumstances

Continuous rotating joints in many executions, light series

� diameters from 1/8” up to 4” � temperature up to 250°C � pressures up to 700 bar � mono-flow or duo-flow, fixed or rotating siphon � for media like water, air, vacuum, steam,

thermal- or hydraulic oil � for fast or slow rotation

Offering the possibility to transport one or more fluids between a fixed point and a rotating point

Hose loading arms and folding stairs for loading truck and railway with hoses or metal loading arms

� facilitating ease of operation and use � avoiding dangerous situations with smart

constructions � longer life of the hoses � higher safety level and lower risk of injuries during

operation by good handling system � environmental protection y guided hose movement � folding stairs up to 10 meter wide, safety cages,

optimisation of existing situations, etc.

Loading technology, individually adapted to the local situation
