Mesur-Fil Fluid Couplings Wichita Mesur-Fil® Fluid Couplings deliver reliable smooth power transmission. To consistently deliver, we select only from the highest quality materials. Our manufacturing and product assembly are completed under the most exacting guidelines and established procedures. The result is unquestioned consistent product dependability. Mesur-Fil Fluid Couplings are ideally suited for direct drive applications between electric motors and gear boxes.
Mesur-Fil Fluid Couplings Design Avantages Mesur-Fil Fluid Couplings allow motors to start unloaded and to reach operating speed with smooth, controlled acceleration. This makes it ideal for applications with high inertia loads. They are available in either constant or delay fill versions. All Aluminum Housing for Low Rotating Inertia Impeller High Temperature Viton Seals Runner Collet Mounted For Ease of Mounting Smaller Sizes One Piece Construction (smaller sizes) Eliminates Leaks.
Mesur-Fil Fluid Couplings Fluid Requirements Figure 2 reveals a typical NEMA B electric motor torque curve together with the particular operating characteristics of a specific coupling with a designated fill level. With no power supplied, all of the fluid is settled at the bottom of the coupling. Slip rate in this condition is 100% with the input free to turn. With the motor starting and increasing in speed to the breakdown point, torque builds in the coupling.

Mesur-Fil Fluid Couplings HC Sizes 7.0-12.4 Input and Output customer supplied. HCM (page 168) (pages 170-171) This is a basic coupling with an input bore for direct mounting on the motor shaft end and a convenient bolt circle for customer-designed output configurations. The Model HCM Fluid Coupling is a complete unit with both input and output flanges. It is intended for installation between two halves of a double engagement gear tooth flexible coupling which is customer supplied.
Mesur-Fil Fluid Couplings Selection and Sizing Fill Levels (NEMA B Motors) The Quick Selection Chart (see Figure 8) provides the correct size coupling and fill level for any standard NEMA B motor within the Mesur-Fil range. It also provides the slip rate that can be anticipated at normal operating speed. Having the correct amount of oil in the coupling is extremely critical to ensure safe and proper operation. Figure 9 shows the effects of either too much or too little fluid.

Mesur-Fil Fluid Couplings Slip Curves Size 7.
Mesur-Fil Fluid Couplings Slip Curves Size 9.4 Maximum speed 3,600 RPM Except HSD-Max.
Mesur-Fil Fluid Couplings Slip Curves Size 12.4 Maximum speed 2,400 RPM Except HSD-Max.
Mesur-Fil Fluid Couplings Slip Curves Size 15 Maximum speed 2,600 RPM (All configurations) C Selection Example: 7.5 HP at 1,750 RPM Pullout torque = 2 * 22.5 lb.ft. = 45 lb.ft. Normal running torque = 7.5 HP * 5,250 = 22.5 lb.ft. 1,750 Pullout torque is obtained at approximately 85% full motor speed and for NEMA B motors, this is approximately 200% normal rated torque. Locate the pullout torque against RPM curve to insure the point is slightly above the drag torque line.
Mesur-Fil Fluid Couplings Modular Design Concept Sizes 7.0, 9.4, 12.4 Configuration HCF Consists of Model HC and input group. The input group is finish bored to fit standard NEMA B motor shafts. The optional output groups available (HCM, HBM) are shown on this page or the HCF output group must be supplied by the customer. Consult engineering for details. HCM The Model HCM Fluid Coupling is a complete unit with both input and output flanges.
Mesur-Fil Fluid Couplings Input Output Note: HCF does not provide an output group. Output group is customer supplied. C HC Fluid coupling with bearing carrier group HC The model HC Fluid Coupling consists of the basic coupling with bearing carrier group and seals installed. Optional output and input groups are available as ahown on these pages or customer supplied. This arrangement provides for a wide range of input and output configurations for ease of installation.
