STD - SD® Series Dosing Screw Pump
The S T D-SD® Dosing Pump is a fully synthetic pump for the precise dosing of a great variety of chemicals in environmental technology and the chemical industry. Its synthetic construction makes it perfectly suited for the gentle and low-pulsation conveyance and dosing of aggressive or non-aggressive chemicals.
With only seven main parts, the S T D-SD® is particularly easy to service and economical.
S T D-SD® series screw pump Dosing Technology
"The S T D-SD® dosing screw pump is ideally suited to the most difficult dosing tasks due to its continuous and virtually pulsation-free conveyance.
We offer our customers comprehensive solutions, from barrel emptying systems to one-component dosing systems.
we are a competent and reliable contact wherever media which is free of solids and media containing solids can be processed. Our team supports you from the development of an approach to finding a solution through to implementation and commissioning on site, as well as with your staff training.
Features of the S T D-SD® Series dosing screw pump
1)universally applicable for many media - even acids and bases
2)continuous low-pulsation conveyance unaffected by fluctuations in pressure and viscosity
3)conveyance volume in proportion to rotation speed with high dosing precision over the entire rotational-speed range
4)reversible direction of rotation and dosing
5)self-priming, no (or low) product input pressure required (depends on material)
6)no dripping or stringing of product due to reverse-flow
7) easy programming of quantity and speed
8)low maintenance, quick dismantling
9)compact and efficient
Wide Spectrum of Applications
The S T D-SD®dosing screw Pump is used primarily for substances with the following properties:
