As the septic services industry advances, a variety of vacuum pump and blower technologies have emerged to meet diverse operational demands. These innovations range from tri-lobe worm screw profile rotors designed for reduced vibrations and noise levels, to rotary vane pumps engineered for extreme conditions, to preassembled gasoline or diesel-powered vacuum pump units for easy installation. With enhancements in air-cooling systems, heat transfer efficiency and environmental sustainability, these technologies embody the strides being made to improve performance, durability and ease of maintenance in septic services equipment.

Presvac Systems PV750
The Presvac Systems PV750 rotary vane pump is designed for continuous full-vacuum operation in extreme conditions. It offers 400 cfm at free air, 350 cfm at 15 inches Hg, a maximum vacuum of 27 inches Hg and maximum pressure of 35 psi. Dual fans and twin ballast ports are designed to efficiently cool the pump. The solid housing with deep cooling ribs allows greater heat transfer from the vacuum chamber. Aluminum fans and shrouding work like a heat exchanger. Multiple manifold and drive options are available for truck, trailer or stationary applications. 800-387-7763; www.presvac.com

Engine and Accessory JUROP HELIX Blowers
Jurop HELIX Blowers, distributed by Engine and Accessory, incorporate tri-lobe worm screw profile rotors, dynamically balanced to reduce vibrations, and designed for vacuum systems that convey air and create a constant negative atmosphere with less input speed and overall power requirements. They are designed with a built-in air injection cooling system. This system of channels — porting — is a Jurop-designed solution to maintain lower blower temperatures and to decrease blower noise levels to the point of not requiring an enclosure. Models are available with CFMs ranging from 280 to 6,400, ATEX Certification, and engineered packaging for mobile applications globally. 305-573-2268; www.eamparts.com

Wallenstein Vacuum 753 Series
The 753 Series vacuum pump from Wallenstein Vacuum is designed for longer service life, incorporating wide vanes that allow up to an inch of wear. It provides 422 cfm airflow at 1,200 rpm and vacuum levels up to 28 inches Hg. Options include air-, liquid- or dual-cooling systems where air injection is combined with liquid cooling. A pump-flushing port is included on the top valve for convenient maintenance. The quick-access housing end plate allows for easy internal inspection with no bearings to pull. Oil lubrication is via a mechanical piston pump driven by shaft rotation or available with a sight-feed valve oil regulator system using vacuum/pressure to draw oil with no moving parts. 800-801-6663; www.wallenstein.com

Westmoor Conde PowerPaks
Westmoor Conde PowerPaks are preassembled gasoline or diesel-powered vacuum pump units. They are easy to install, according to the maker, and include a heavy-duty steel base with aluminum diamond plate trim and belt guard. Rigid assembly is designed to ensure minimum vibration and maximum power. They are available with either vacuum only or vacuum/pressure pumps. A wide range of cfm options ensure the PowerPak is matched to the tank size and application. Units are powered with optional Honda GX Commercial Series gasoline engines or Hatz industrial air-cooled diesel engines. Units can be easily transferred to another tank system when needed. 800-367-0972; www.westmoorltd.co
