Together with the rotor, it forms the heart of the pump: the mechanism that grips the mortar and pushes it through the hose under pressure works through the coordinated operation of these two parts. In this article, we explain what a plastering machine stator is, how it works, when it should be replaced, and how to choose the right spare part.<\/p><p><strong>Note:<\/strong> The word \u201cstator\u201d is also used for electric motors and alternators (the stationary winding section of a motor). This article covers the <strong>stator in plaster and mortar machines<\/strong>\u2014that is, the rubber housing of the progressive cavity pump.<\/p><h2>What Is a Plastering Machine Stator?<\/h2><p>ASE plaster and mortar pumps operate on the <strong>progressive cavity pump<\/strong> principle. This system has two main components:<\/p><ul><li><strong>Stator:<\/strong> The <strong>stationary<\/strong> housing, made from special wear-resistant rubber, inside which the rotor rotates. Its inner surface has a spiral cavity shaped to match the rotor\u2019s helix.<\/li><li><strong>Rotor (helical shaft):<\/strong> A helical shaft made from hardened metal that rotates inside the stator.<\/li><\/ul><p>The stator is stationary while the rotor moves. As the rotor turns inside the stator, sealed cavities form between them, allowing the mortar to move continuously and without pulsation. The stator\u2019s rubber construction makes a tight seal against the rotor, keeping these cavities leak-proof\u2014the pump\u2019s pressure and flow rate depend largely on the quality of this contact.<\/p><h2>What Does a Stator Do?<\/h2><p>The stator\u2019s purpose is to form <strong>sealed conveying cavities<\/strong> between itself and the rotor. These cavities ensure that:<\/p><ul><li>Mortar is conveyed forward smoothly, without flowing back.<\/li><li>Stable flow and pressure are achieved.<\/li><li>Spraying is even and consistent.<\/li><\/ul><p>As the rubber stator wears over time, its contact with the rotor weakens. The cavities are no longer fully sealed, mortar starts to flow back, and pump efficiency drops. That is why the stator is a critical component that directly determines machine performance.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\r\n\t\t<div class=\"default no-position show_shadow rs-sticky-default elementor-element elementor-element-17734db e-flex e-con-boxed e-con e-parent\" data-id=\"17734db\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\r\n\t\t<div class=\"default no-position show_shadow rs-sticky-default elementor-element elementor-element-bb20582 e-flex e-con-boxed e-con e-child\" data-id=\"bb20582\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\r\n\t\t\t\t<div class=\"elementor-element elementor-element-2c3198e elementor-widget elementor-widget-image\" data-id=\"2c3198e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/desinoval.com.tr\/product-detail\/ase-sm-5-premium\/\">\n\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"830\" height=\"541\" src=\"https:\/\/desinoval.com.tr\/wp-content\/uploads\/2026\/08\/SM-5-SM-PLUS.webp\" class=\"attachment-full size-full wp-image-32629\" alt=\"\" srcset=\"https:\/\/desinoval.com.tr\/wp-content\/uploads\/2026\/08\/SM-5-SM-PLUS.webp 830w, https:\/\/desinoval.com.tr\/wp-content\/uploads\/2026\/08\/SM-5-SM-PLUS-300x196.webp 300w, https:\/\/desinoval.com.tr\/wp-content\/uploads\/2026\/08\/SM-5-SM-PLUS-768x501.webp 768w, https:\/\/desinoval.com.tr\/wp-content\/uploads\/2026\/08\/SM-5-SM-PLUS-413x269.webp 413w\" sizes=\"(max-width: 830px) 100vw, 830px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\r\n\t\t<div class=\"default no-position show_shadow rs-sticky-default elementor-element elementor-element-c36109f e-flex e-con-boxed e-con e-child\" data-id=\"c36109f\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\r\n\t\t\t\t<div class=\"elementor-element elementor-element-a2bd770 elementor-widget elementor-widget-image\" data-id=\"a2bd770\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/desinoval.com.tr\/product-detail\/vp-500-dhl\/\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"830\" height=\"541\" src=\"https:\/\/desinoval.com.tr\/wp-content\/uploads\/2026\/07\/VP-500-DHL-ASE-MAKINE-1.webp\" class=\"attachment-full size-full wp-image-32630\" alt=\"\" srcset=\"https:\/\/desinoval.com.tr\/wp-content\/uploads\/2026\/07\/VP-500-DHL-ASE-MAKINE-1.webp 830w, https:\/\/desinoval.com.tr\/wp-content\/uploads\/2026\/07\/VP-500-DHL-ASE-MAKINE-1-300x196.webp 300w, https:\/\/desinoval.com.tr\/wp-content\/uploads\/2026\/07\/VP-500-DHL-ASE-MAKINE-1-768x501.webp 768w, https:\/\/desinoval.com.tr\/wp-content\/uploads\/2026\/07\/VP-500-DHL-ASE-MAKINE-1-413x269.webp 413w\" sizes=\"(max-width: 830px) 100vw, 830px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\r\n\t\t<div class=\"default no-position show_shadow rs-sticky-default elementor-element elementor-element-6074354 e-flex e-con-boxed e-con e-parent\" data-id=\"6074354\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\r\n\t\t\t\t<div class=\"elementor-element elementor-element-fa6cd99 elementor-widget elementor-widget-text-editor\" data-id=\"fa6cd99\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2>When Should the Stator Be Replaced?<\/h2><p>The stator is a <strong>wear part<\/strong> by nature (like the rotor).

Always operate the pump with material in it.<\/li><li><strong>Clean it after every use:<\/strong> Mortar left to dry inside wears down the stator and can cause blockages.<\/li><li><strong>Use the correct tightening adjustment:<\/strong> Some stators are clamped or adjustable; the rotor-stator contact should be neither too loose nor too tight.<\/li><li><strong>Use genuine, compatible parts:<\/strong> A stator suited to your machine model helps maintain efficiency and prevents rotor wear.<\/li><\/ul><h2>Choosing the Right Stator: Model Compatibility Matters<\/h2><p>ASE machines use different rotor-stator sets depending on the pump assembly (for example, D 6-3, D 7-2,5, and D 8-2, as well as clamped \u201cLIGHT\u201d stator options). The wrong size will deliver neither efficiency nor long service life.
