  • H5535 Actuator

    The H5535 series actuator combines the rugged design of roller screw technology with the efficiency and reliability of an AC servo motor. This results in an actuator that is brushless for reduced maintenance, provides position feedback without external devices, maintains position accuracy during loss of power without a homing sequence, outlasts ball screw designs by doubling the travel life, and is available in thrust ranges of 500 lbs (2.2 kN) to 40,000 lbs. (178 kN). The high thrust and high duty cycle of the H5535 series make it an excellent replacement for hydraulic cylinder applications. When compared to a hydraulic cylinder, the lower cost of operation in energy savings and the elimination of contamination issues related to hydraulic oil leaks, make the H5535 a perfect choice to upgrade existing hydraulic actuators.

  • Graymills Double Diaphragm Ink Pumps

    For applications requiring controlled flow rates from a trickle to 40 gallons per minute. Especially suited to the requirements of bottom printing corrugated lines, where a single pump provides both supply and suction return.

    These pumps operate by the movement of two flexible diaphragms which move back and forth, alternately filling and emptying two chambers. Flow is controlled with the air inlet valve, which then determines pump speed. A variety of applications are possible because the pump’s inlets and outlets can be configured in different ways, such as “one-in one-out”, “1-to-1”, “two-in two-out”, or “2-to-2”. In the 1–to-1 option, one color is sent to the deck. In the “ 2-to-2” configuration, you can deliver one material and also draw it back, or deliver two inks to two different decks. Diaphragm pumps do have a pulsating flow and are best use with a Graymills surge suppressor/filter.

  • Graymills PPS Ink Pumps

    For narrow web flexo and rotary screen applications, and light to heavy viscosity inks, coatings, and adhesives (including UV/EB), requiring flow rates of 1.5 GPM or less. If flow requirements are above 1 GPM, consider model PPL for slower running speed and longer tube life. Available with electric gear motor with electronic variable speed control (115/230 VAC) 50/60 Hz electric gear motor or variable speed air gear motor (28 CFM@80psig/792.9 LPM @ 5.4 bar).

  • Graymills PPL Ink Pumps

    For mid to wide web flexo, gravure, and rotary screen applications and light to heavy viscosity inks, coatings and adhesives (including UV/EB), requiring flow rates of 4.5 GPM or less. Available with electric gear motor with electronic variable speed control (115/230 VAC) 50/60 Hz or ATEX electric gear motor with variable speed control (230/460 VAC, 3 Ph) 50/60 Hz.

    Optional “Quick Change” removable head Model PQL. Pump head/tube changes are accomplished in seconds without tools. Simply pull the lock-pin, remove the used head, and replace with another head loaded with clean tube. PQL models include all of the features of the standard PPL models. “Quick Change” heads can be retrofit to Graymills peristaltic pumps made since January 2005.

  • Graymills Dual Head Pumps

    Two peristaltic pump heads powered by a single motor allow the pump’s heads to be individually set to supply or return. This ability, coupled with the pump’s variable speed capability and ability to reverse direction, allows for several pumping configurations:

    • Supply one ink to two separate decks
    • Supply two different  inks to two separate decks
    • Supply and return one ink to one deck

    These pumps are available in PPS or PPL versions, have standard quick change heads, eight position adjustable head orientations, and remote mounting of controls with a 16’4” (5m) cord. Available with electric gear motor with electronic variable speed control; consult factory for explosion proof model. CE compliant models available.  Optional hard coat anodized head with stainless steel rotors (PQL only).
