Signs You Need Make-Up Air
Introduction
The lack of make-up air in a building can cause serious problems. Many times the problems are not even recognized and show themselves in ways that most people do not think about. A properly designed and installed ventilation system provides environmental control by avoiding negative pressure. Uncontrolled infiltration of air through window sashes, doors and

Fluid Engineering is proud to serve as your local distributor for Seepex Progressive Cavity Pumps, available in the following series:
N - Standard Progressive Cavity Pump
Seepex pumps of product group N form the basic product group of all Seepex progressive cavity pumps. They can be supplied with various rotor/stator geometries (conventional, 6L and Tricam geometry) and can be used in almost all branches of industry for pumping low-viscous to highly viscous media with or without solids. Numerous application advantages ensure an especially economical application.
Flow Rate 0.132 USGPM - 2,200 USGPM
Pressure up to 720 PSI
Advantages and Characteristics
- Installation capabilities in any position
- Elevated, self-priming rate, including with gas-liquid or air mixtures reaching 8.5 mWS
- Low pulsation, steady pumping
- Delivery flow is reversible due to direction of rotation
- Large-sized spherical entrance port
Seepex pumps of product group T are used for high-consistency material with low degree of intrinsic flowability or none at all. For these pumping products, the suction lift capability of a standard pump of product group N is no longer sufficient to suck them into pipings. For this reason, pumps of product group T are equipped with a feed hopper and facilities for safe product feeding. It is successfully used in almost all branches of industry to pump viscous to airtight products.
Flow Rate 0.220 USGPM - 2,200 USGPM
Pressure up to 540 PSI
Advantages and Characteristics
- Pump with feed hopper and conveyor screw
- Pitch and diameter of the conveyor screw is adapted to the operation conditions for optimum product feed.
- Optimum solutions for various viscosities and characteristics of the conveying medium.
- Numerous ranges, optionally available in block designs or with free shaft ends.
- Service-friendly due to plug-in connections between rotating unit and drive.
Seepex pumps of product group D are used for delivering and dosing small quantities in almost all branches of industry. They are especially suited for low-pulsation delivery of low to highly-viscous media as well as media containing solids and chemically aggressive media while achieving a high dosing accuracy.
Flow Rate 0.053 USGPM - 264 USGPM
Pressure up to 360 PSI
Advantages and Characteristics
- Modular system enables a rapid and simple inter-conversion of various sizes available
- Low-pulsation pumping
- Highly accurate dosing with a deviation of ± 1%
- Service-friendly with plug-in connections positioned between the drive and rotating unit
- For all pumping liquids, various material combinations are available
Seepex pumps of module range CS are used primarily in the food, pharmaceutics, cosmetics and chemical industry. The pumps with CIP (Cleaning In Place) and SIP (Sterilisation In Place) capabilities meet the highest requirements for gentle handling, hygiene, cleaning and sterilization and comply with the regulations of the 3-A Sanitary Standards of the USA and the EHEDG directives.
Flow Rate 0.132 USGPM - 572 USGPM
Pressure up to 360 PSI
Advantages and Characteristics
- Product deposits are prevented through optimized pump housings no clearance volume
- Easy-to-service due to plug-in connections between drive and rotating unit – no special tools required for mounting/dismantling
- Enhanced service-friendliness through easily mountable joints
- Residual-free cleaning is simplified through rotating inside parts and exceptional quality surfaces on the housing walls
- FDA approved stator material and secondary seals deliver high product safety
- Hygienic shaft sealing achieved through mechanical seals proven and adjusted to the particular application
- Sterilization in Place (SIP) utilizing superheated steam may be used during the pump’s cycled operation
- Cleaning in Place (CIP) rinsing that include elevated flow rates in the suction casing enable bacteria-free and residual-free cleaning
- CS range pumps adhere to the EHEDG directives and the regulations of the 3A-Sanitary Standards of the USA
Seepex semi-submersible pumps of product group E are installed vertically. They pump liquids of different viscosities, which may be abrasive or even aggressive. Due to their high degree of efficiency, the low space requirements and the maintenance-friendly design, seepex semi-submersible pumps feature low operating cost and are thus a cost-efficient alternative to other pump systems. Pumps of product group E are self-priming.
Flow Rate 0.132 USGPM - 1,320 USGPM

Advantages and Characteristics
- Self-priming feature
- Low pulsation, steady flow
- Pumps shear sensitive products in a gentle manner
- The NPSH value available can be increased
Pumps of product group W can be used in almost all industries. They are designed to handle liquids of all viscosities and even products with high solids contents. Due to the simple construction wobble pumps are cost effective and easy to handle.
Flow Rate Up to 44 USGPM
Pressure up to 60 PSI
Advantages and Characteristics
- Non-complicated pump construction makes it economical and service friendly
- Compact, short design with directly flanged drive, block design, effectively saves space
- Conveying elements are rapidly exchanged as a result of rotating unit with only one joint
Apart from applications in processing municipal and industrial waste waters, Seepex macerators are also used in a multitude of other branches of industry. They macerate the solid and fibrous components in the conveying medium, thus increasing the operating safety and service life of the downstream seepex pumps and other machinery. The degree of maceration can be varied depending on the flow rate, the drive speed and the shear plate design and can thus be adapted to diverse application conditions.
Flow Rate 8.8 USGPM - 660 USGPM
Advantages and Characteristics
- Two ranges, each with two sizes
- With the use of shear plates, controlled macerating is carried out using variable speed drives and different large apertures
